We were fortunate enough to have Mrs. Woodward come and work with us on understanding the forces that allow things to fly. This post is a place to comment on what we know, what we didn't know, what we found interesting and what we still don't quite understand.

FORCE- HOW THINGS FLY
I thought that learning about force and aerodynamics was very interesting, we got taught a lot of interesting facts for example
747-400 can weigh up to 40,000 kilograms. I didn’t realise how planes stay up in the air but now I have a good understanding of how they do. The main things that we learnt today were, drag, weight, thrust, and lift. Before we learnt about aerodynamics today I didn’t know much for example I didn’t know that aerodynamics comes from 2 Greek words aeries, concentrating the air, and dynamis which means force and I also didn’t know that aerodynamics is the study of forces and the resulting motion of objects through the air.
I didn’t quite understand the lift part because I thought it was quite confusing but after she went through it all and explained it clearly I understood more. Overall I think it was very fun to learn about aerodynamics.
On the 16th of Semptember 8H had Mrs. Woodward come in to our class to teach us, "force and how things fly".
At first some little things blew over my head and i still didnt know how on earth planes and other flying objects can stay up in the for such a long amount of time.
It was when Ms. Woodward started explaining force i found it easier to understand.
First we learnt what Aerodynamics means.
Aerodynamics is a study of forces and the resulting motion of objects through the air. It comes from 2 Greek words; aerios - concerning the air and dynamics - force.
We learnt the 4 forces which included-
-Lift
-Weight
-Thrust
-Drag
As we watched the powerpoint about these 4 forces there were at least several facts on each of them and these dot points really helped me understand how flying objects can stay in the air.
For the force lift the diagram of the planes wing pointed out that planes wings are like that, which i have never noticed. This taught me how the wings work on the plane and why they are so important to the plane.
To rember the shape of the aerofoil, i picture it as a shape of a whales body as it is rounded at the top and goes to a point.
Usally the top part of the aerofoil is curved and the bottom is flat, As the plane flies air rushes over the wings. The air that travels over the top of the aerofoil has to travel further that the bottom so it is quicker than the
air passing along the bottom of the wing.
Miss Woodward talked about 'gravity' which i already had known about. Gravity forces all objects on earth to the ground. With this i still dont quite understand how such a heavy thing, being a plane, can stay up in the
air for such a long amount of time.
i thought it was interesting how the 747-400 (which is a type of aeroplane) can weigh up to such a heavy weight being 400,000 kilograms
We completed some activities with Mrs. Woodward.
One of the was the paper test.
in this 2 people had a sheet of paper and dropped it from the same height 3 times, we then did this again with the paper folded in half, and again with the paper folded in half again.
the results in the end was the paper that landed on the ground the slowest was the whole paper with no folds,
and the paper that landed on the ground the fastest was the quarter paper that was folded twice.
Another activity we did was making paper aeroplanes. That is on the next blog where i have left a comment.
I still dont understand completly how such heavy things can fly in the air, and still they carry luggage and people which makes them even heavier.
Other things i now understand good, all of the points we learnt on the 4 forces are clear to me and i understand how they all work.
I enjoyed this day. I thought it was good how we learnt about these forces.

for boomerang come back we were fortunate enough to have ms woodward teach us about force and aerodynamics. she was really good because she knew what she was talking about so it made it easier to understand.
she told us all about areodynamics and we did a little exercise to teach us more about aerodynamics. we had an A4 sheet of paper and we timed how long it takes for it to touch the ground. then we folded it in half, the in half again. the bit that wasnt folded took the slowest time because it had more air resistence than the piece that was folded twice which took the quickest because it was the smallest and it had less drag, as ms woodward told us.
we were told about the four main flight principles, which were
Lift- the high pressure at the bottom pushes the wings upwards to lift the plane off the ground.
Drag- as an object falls it pushes air out of the way. in return the air pushes on the object. this push is called air resistence. th faster an object falls the greter the air resistence.
Thrust- the push that keeps the plane moving forward is called thrust. something needs to push the plane forward. often an engine is used to push it forward,
Weight- aeroplanes are forced to the ground by gravity.
i learnt a lot about forces and aerodynamics and it was pretty fun too! it wasnt as boring as some of the other tasks we've done
FORCE-HOW THINGS FLY
in 8h we had a teacher come into our room and teach us about arodynamics and how planes and stuff fly, A 747-400 can weigh up to 400,000-kg.aeroplanes,birds are forced towards the ground by gravity. the shape of a wing is called a aerofoil. we also learnt about 4 other things,
lift- The high pressure at the bottom of the aeroplane pushes the wings upward to give the plane lift to get off the ground.
Thrust- The push that keeps the plane moving forward is called thrust.something needs to push the plane forward, often it is an engine that pushes it forward.
weight-aeroplanes are forced towards the ground by gravity.
Drag- as a object falls it pushes out air out of the way. in return the air pushes on resistence.The faster an object falls the greater air resistance.
When Mrs. Woodward came in i didn't know that much about aerodynamics at all. But by the time i left i did. The things she taught us was mainly about -Thrust, Drag, Lift and weight.
I thought it was amazing about the weight of an aeroplane and how hey can get up in the sky so easily.
I found 'Lift' the easiest to understand
Lift- the high pressure at the bottom pushes the wings upwards to lift the plane off the ground.
by Chloee :D
in 8h we were lucky getting a teacher coming in and telling us about forces. lift the high pressure at the bottam push's the wings up to get the plane off the grown. thrust the push that keeps the plane moving is called trust somthing has to push the plane mostly likey engines but you could also have rotors and propellers and that would get it going forward. weight the planes are furced by gravity a plane could wieght up to 400,000. drag has a object falls it push's air out of the wayin returnthe air push's on the object that is called air resistence. faster the plane goes or object bigger the air resistence
How Thing Fly
On the 16th of september we 8h had mrs woodward come in and also tech us about force and how things fly this is when we flew our planes. i learnt that the main thngs you needto know about how how planes fly is LIFT THRUST DRAG and WEIGHT.
LIFT the shape of an weroplane wing is called an aerofoil. usally the top is curved and the bottom is flat. this gives low air pressure on the top of the wing.
THRUST the push that keeps a plane moving forward is called thrust.
- propellers (single to win engine planes)-rotors9helicopters)-engines( jet aircraft-blast hot gasesout the back of the plain.)
8H had mrs woodward come in and teach us bout.
-Lift
-weight
-thrust
-drag
as we watched a powerpoint on -Lift,weight,thrust and drag we also learnt bout aerodynamics and force and how they keep and aeroplane from sky diving into the ground.
On September the 16th 8H we were fortunate to have Ms Woodward come to our class and teach us about 'Force'.
I didn't really have a clue on how things flew but it was lucky we did have Ms Woodward, once she started expaining things I strated to understand how things were flying.
First Ms Woodward taught us about Areodynamics it is two Greek words:
Aerios - connecting with the air
Dynamics - force
Aerodynamics is the study of forces and air resulting motion of objects through thr air.
Then Ms Woodward told us there was four forces on a plane, they were Lift,Weight,Thrust and Drag. First off we had to do a test on Drag.
We had to be with a partner and we were given An A4 sheet of paper and we had to find which fold was quickest and which was longest. To do the test you had to drop the paper when it wasn't folded, then drop the paper when you had folded it in half, then drop it when you had made it into a quarter, while you droped the paper you had to time to see which was quickest. My partner was Nick and he did the timing and I would drop the paper. Our shortest time was 0.91 and that was with the quarter fold because the paper was heavier than the others and it had less drag than the others. Our longest time was 2.70 with the sheet of paper not folded at all it went the longest of all becuase it had more air resistence.
Lift- The wings are pushed upwards and the plane is lifted off the ground,when this lift balances the weight of the plane will fly at a steady height.
Weight- Every object in the world has weight. A 747-400 (big plane) can weigh up to 400,000 kilograms. Aeroplanes are forced towards the ground by gravity.
Trust- The push that keeps a plane moving forward is called thrust, there are things that help keep it moving they are such as:
Propellers
Rotors
Engines
Something has to help the plane lift off.
Drag- As an object falls it pushes air out of the way. In return he air pushes on the object. This push is called air resistence. The faster an object falls the greater the air resistence.
Thanks to Ms Woodward I now know more things on Forces and how things fly.
FORCE--
'How things fly' was the topic we did on the 16th Sep. We had
Mrs. Woodward teaching us. She showed me a complete understanding of 'Aerodynamics'.
- The 747 400 can weigh up to a total of 40,000 kilograms.
- Aerodynamics come from 2 greek words, aeries means air and dynamis means force.
lift- The high pressure at the bottom of the aeroplane pushes the wings upward to give the plane lift to get off the ground.
Thrust- keeps the plane moving forward.
weight- Gravity forces the plane down tho the ground.
Drag- as a object falls it pushes out air out of the way. in return the air pushes on resistence.The faster an object falls the greater air resistance.
When we were learning about force i thought its very interesting because a thing that big (planes) can actually get off the ground. I learnt that they need a special angle on the planes wing to get the lift it needs. I was interested that a 747-400 can weigh up to 40,000 kilograms. i didnt realy understand how the planen lifts up but i understand now.
8h had a good time listening to that techer and how planes fly.
As a class 8h had Miss Woodward come into our classroom and teach us about flight principles.
It was fun because I like planes and how they work so I found this lesson to be really interesting to me.
What I learnt was that the word AERODYNAMICS comes from two Greek works AERIOS: concerning the air and DYNAMICS: which means force. AERODYNAMICS is the study of forces and the resulting motion of objects through the air.
What I found most interesting for me was the page where we put down what was lift, drag, thrust, weight. Out of them this is what I found interesting:
Weight: Every object on earth has a weight. A Boeing 747 can weigh up to 400,000 kilograms. Aeroplanes are forced towards the ground by gravity.
I don’t understand how an Aerofoil shape can lift a 400,000 kilogram plane in to the air.
I also don’t understand the drag part but I would love to learn more about it.
We did a little activity that explains a lot to me that I did not know before.
We tested a whole paper first.
Test1: 1.82
Test2: 2.55
Test3: 1.87
Average: 4.99
The first test was not really a surprise to me because we knew that the whole paper would take a long time to hit the floor.
We folded the original piece of paper in half for our second test.
Test1: 1.38
Test2: 1.41
Test3: 1.65
Average: 3.34
The second test was not much of a surprise to me because we folded the original piece of paper in half and that made the paper smaller. So that means that there was not that much wind hitting the paper and slowing it down as much as the first piece
We now made that original piece of paper and folded it so it made a quarter.
Test1: 1.06
Test2: 1.20
Test3: 1.20.
Average: 2.66
The 3rd test was not a surprise either because the paper was a quarter so not much wind would have hit it and that made it do fast until it hit the ground.
Here are some more results about the prac:
The fastest one was the Quarter folded piece of paper because it had less drag.
The slowest on was the whole piece of paper because there was heaps more drag.
I learnt that as a plane is flying air rushes over the top of the wing.
If there is no air going over the top of the wing the plane will stall and fall because I have a computer game it is flight simulator and if you lift up the front of the plane to much the air can’t go over the top of the wing and you just fall.
I found this really interesting: The wing is pushed upwards and the plane is lifted off the ground. When this lift balances the weight of the plane the plane will fly nice and there will be no turbulence.
I also learnt about thrust and engines
Propellers ( single or twin engine planes )
Rotors ( helicopters )
I found this really interesting and fun to do as a class.
As a class 8H were lucky enough to have Miss Woodward come into our classroom and teach us about flight principles.
The word "Aerodynamics" comes from two greek words: aerios, concerning the air, and dynamics, which means force.
AERODYNAMICS is the study of forces and the resulting motion of objects through the air.
As a class 8H did a activity in pairs, i was with leigh and its where we got a sheet of paper between the two of us and we had to drop it from a distance and see how long it took to get to the ground after we did three tests on the whole sheet of paper we calculated the average and wrote it down, we then folded it in half and dropped it from a distance to see how long it took to get to the ground, after three tests we calculated the average, the we folded the sheet of paper in half again so it made it into a quarter piece and repeated what we did to the original sheet of paper.
Here are the test results for the activity.
To start with we tested the whole sheet of paper:
Test 1 - 1.82 secs
Test 2 - 2.55 secs
Test 3 - 1.87 secs
I had an idea that the whole sheet of paper would take a while to get to the floor because it would have a lot of drag.
Next we tested the original sheet of paper folded in half:
Test 1 - 1.38 secs
Test 2 - 1.41 secs
Test 3 - 1.65 secs
I had a thought that the half folded sheet of paper would hit the ground quicker because it was a smaller size piece of paper than the original sheet and it also had less drag.
Then finally we tested the sheet of paper folded into a quarter:
Test 1 - 1.06 secs
Test 2 - 1.20 secs
Test 3 - 1.20 secs
I knew that the quarter piece of paper would get to the floor the quickest because its small and it has hardly and drag.
These are some more results for the activity leigh and I did as a pair.
The fastest test was the quarter folded piece of paper because it was smaller which gave it less drag.
The slowest test was the whole piece of paper because it was bigger which gave it heaps more drag.
What i found very interesting was when we did the worksheet called "Forces acting upon a plane".
The sheet had four boxes on it and in each box we wrote about LIFT, THRUST, WEIGHT and DRAG.
Here are some facts about each one.
LIFT.
-The wing is pushed upwards and the plane is lifted off the ground.
When this lift balances the weight of the plane will fly at a steady height.
-The shape of an aeroplanes wing is called an aerofoil.
-Usually the top is curved and the bottom is flat.
-As a plane flies air rushes over the wings. The air travelling over the top has to travel further and therefore faster than the air passing along the bottom.
-This gives low air pressure on the top of the wing.
THRUST.
-The planes engines pushes the aircraft forwards and up in the air and if there was no thrust the aircraft would not fly.
-The push that keeps a plane moving forward is called thrust.
-Propellers (single or twin engine planes)
-Rotors (helicopters)
-Engines (jet aircraft blast hot gases out of the back of the plane)
WEIGHT.
-Every object on earth has a weight.
-A Boeing 747 can weigh up to 400,000 kilograms.
-Aeroplanes are forced toward the ground by gravity.
DRAG.
-As an object falls it pushes air out of the way. In return the airpushes on the object. This push is called air resistence.
-The faster and object falls the greater the air resistence.
I found this a good experience to learn from and it was also ver fun to do as a class.
I also wasn't here for this activity. By reading everyone else's comments I now understand "forces", I understand lift, drag, thrust and weight, gravity and aerodynamics.
I know where the word "aerodynamics” comes from and I know how much a 747-400 can weigh. I understand how the air rushes over the plane and keeps it up. I don't feel a need to go through everything as what I have to say is only what I learnt from the others.
The main thing is that all forces act against each other but they also act in a way that is together, keeping such heavy, big things in the air. Each force has a different use, but take one away and that's it, it won't fly.
I have explained what, lift, drag, thrust and weight are on the paper airplanes page, but just to say it again lift is as a plane fly’s and air rushes through the wings, drag is the faster something falls, the greater the air résistance, weight is when something drops to the ground, thrust is the what keeps the plane moving forward and gravity is what goes up, must come down.
My blog for force-how things fly:
On the 16 September we had an investigations lesson. I thought it was going to be a normal lesson with ms A teaching us but I was wrong. Instead of having ms A teach us we had Mrs. Woodward teach us. Mrs. Woodward knew heaps about aerodynamics and force.
I was interested to find out about “how things fly because I didn’t get how a plane could fly with wings (I didn’t know that the wings moved), I was very surprised when I was told that a 747-400 can weigh up to 40,000 kilograms.
The main forces are:
Lift
Weight
Thrust
Drag
I was very interested to know that as an object falls it pushes air out of the way, in return the air pushes on the object. This push is called air resistance, the faster the object falls, the greater of air resistance. I was unsure whether this was true, but when we did the experiment where we folded paper then dropped it 3 times then folded it in half again and dropped it I started to understand.
This experiment proved that this is true because Molly and I got results that proved that the faster the paper fell the more air resistance there was. I thought that the quarter piece of paper would fall the fastest because it is small and has less area. I was right in our experiment the quarter piece of paper test 2 fell the fastest at a time of 1.04 seconds
I was interested, but also curious how Gravity forced aeroplanes towards the ground. I learn’t more about gravity and more about how every object on earth has weight.
Mrs. Woodward then went further in explaining lift and gave us lots of facts during her presentation. I was told that a wing of an areoplane has a curved top and a flat bottom, this helps the areoplane fly, as a plane flies air travels over and under the wing. The air traveling over the wing has to travel further because it is a further distance and therefore the particles move faster, the bottom is flat so the particles don’t have to travel as far this makes the particles travel slower than the particles that go over the top of the wing. I was then told that the wings actually move and if the wings did not move the plane would not be able to lift of the ground.
I thought the lesson was organized and interesting. I really liked how we did experiments to prove that what we were learning was correct, even though we were learning it was still fun and very enjoyable. I would really like to do a lesson like this again, because after we had completed a task we moved on straight away we didn’t have to wait.
On the 16th of September
8H were lucky enough to have Ms Woodward come into our class to teach us all about “Force and how things fly”
Our class learnt what Aerodynamic was:
-The meaning of Aerodynamic is the resulting motion of objects through the air. It comes from 2 Greek words…
Aerios- concerning the air.
dynamics- force.
After that we went on to learn about the 4 forces which included:
-Lift
-Weight
-Thrust
-Drag
The PowerPoint was explaining a few dot points on what each of these forces were and what they do, this really helped me to understand and retain information on what force is.
The most interesting bit I found in the PowerPoint was, how the 747-400 (aeroplane) can weigh up to 400,000 kilograms.
We did an activity called “The paper test.“ we did this in pairs, it started off with I A4 sheet of paper, then we had to drop it from the same height 3 times, we did this over and over again each time folding it in half, this was to see which fold was the slowest at hitting the ground and which fold was the fastest hitting the ground, the slowest was the whole piece of paper with no folds, and the fastest was the paper folded twice.
I have learnt a lot of new interesting facts about “Force and how things fly” I really enjoyed having Ms Woodward as a teacher and hope I can retain most of this knowledge for later years to come.
The paper plane activity was fun cuz we got 2 make paper planes and fly them it was fun we learnt lots about drag, lift, thrust and w8
W8= every object has weight *a 747 can weight up to 400,000 Kg it’s kinda amazing how that must weight can fly when like a fat man can harldy jump a foot of the ground and over 400,000 Kg it’s pretty amazing how they do that .
We also learnt about thrust in planes and how it’s needed Thrust is the push that keeps a plane moving like on small planes Propellers on older planes and rotors on helicopters and a jet engine on a fighter jet
We also learnt about Lift and Drag.
Drag- as an object falls it pushes air out of the way in return the air pushes the object. This push is called resistance. Faster an object falls greater the resistance.
We learnt about Lift. Lift is the shape of an aeroplane wing the shape is called aerofoil
well in that class i found it amazing that a 747 of 40 tons could get off the ground and i found that amazing not only that it could get off the ground but that it could handle the pressure and forces placed on it.before this class i new a fair bit about forces mainly because i had a model plane and for racing,in racing you have to have your aero set right you can ajust it so the car has less down force that will make the car accelerate alot faster but you will loose alot of your grip for cornering. but in a plane you don't need grip for cornering so the aerodynamics are set for lift witch is one of the most amazing forces i think if its able to get 40 tons off the ground there are more than one force acting on a plane that help and pervetn it from getting off the ground Thrust, Drag, Lift and weigh
drag and weight both help prevent the plane for getting off the ground weight because of gravity and drag because its what makes things slow and stop. thrust and lift counteract these forces thrust counteracts drag but not only that it creates lift witch counteracts weight.
overall it was an interesting class and i enjoyed it alot!!
In therm 3 of 2008, 8H had the pleasure of having Mrs. Woodward in our class to teach us 'Force and how Things fly'.
The first activity we participated in was watching a PowerPoint about aerodynamics, aerodynamics is the study of forces and the resulting motion of objects through the air. Aerodynamics comes form two Greek words: Arios and Dynamis, meaning air and force.
We also learned that there were four forces that are prerequisite for anything to fly, these forces are:
-Lift
-Weight
-drag
-Thrust
LIFT
To create lift on and object it must have wings in an aerofoil shape. The aerofoil shape has a similar shape to a whale's body. Its task is to create more air pressure under the wing then over it.
DRAG
As an object falls, it pushes air out of it's way. In return the air pushes back on the object, this is drag. The faster the object falls the greater the drag.
THRUST
Thrust is the push that propels the object forward.
Examples of thrust are:
-Propeller
-Rotors
-Engines
The thrust behind a boomerang is your hand.
WEIGHT
Weight is the force that determines how fast an object falls to earth, e.g. a 10kg item would fall faster then a 5kg item.
We also talked about gravity; gravity is the force that pulls us to the ground. We preformed an experiment which would show us how gravity works, the experiment was get a piece of paper, drop it then time how long it would take to hit the ground, repeat three times, find an average and then fold it in half, drop it again, time it again, then fold it into quarters and repeat recording your results as you go. The aim of this experiment was to see which piece of paper (full, half, or quarter) would fall the fastest, the quarter was the fastest because it was smaller and had less wind resistance, the full piece of paper was the slowest because it had the most wind resistance and was lighter.
I felt fascinated as I gathered this information because, I knew nothing about aerodynamics and how boomerangs flew through the air, I just thought it was a flat plank of wood that you threw that came back to you I didn’t know about the aerofoil shape or anything.
force-how boomerangs fly
On the 16th of september
ms. woodward came into 8h and taught us about how boomerangs fly and aerodynamics it was interesting to learn about them because i didnt no much about those topics.We learnt about lift,drag,weight,thust.Aerodynamics is the study of forces and the result into motion of objects through the air. It comes from 2 Greek words: aerios ~ concerning the air and dynamics.I think it was good that ms.Woodward presented all the facts on a powerpoint because it was a different and it would have been pretty boring if she just talked about it and it helped me understand it more.It helped me understand force and why planes and boomerages fly. :)
In investigations I learnt a lot on how things fly from Mrs Woodward. I thought the session was very interesting and fun too.
Our class learnt about Aerodynamics which comes from two Greek words.
AREIOS: concerning the air
DYNAMICS: which means force
Our class also learnt that aerodynamics is the study of forces
and the resulting motion of objects through the air.
Through Aerodynamics I learnt that their are four air principles behind the why of which things fly.
Lift is the shape of a aeroplanes wing which is called aerofoil. Air rushing into the wing splits in two, one part of the air goes under the wing while the other part goes over. The air going over the top of the wing goes faster than the air going along the bottom of the wing, the bottom half then has greater pressure than the top half, which therefore lifts the aeroplane up.
Weight: every object on earth according to gravity has a weight. This weight forces aeroplane or other flying objects to the ground.
Thrust is the air push that keeps a plane or object moving is called thrust. Many vehicles use this such as helicopters that use rotors, and engines like with jet aircraft that use hot gases out the back of the plane.
Drag Can also be known as air resistance. As an object falls it pushes air out of the way, and in return air pushes off the object. This push of air is called air resistance, the faster an object falls the greater the air resistance will be.
After learning about Aerodynamics Mrs Woodward got the class to a paper experiment with on how long the paper can stay above the ground. After the class completed the experiment we found out that the more area something has the longer it will take to fall to the ground due to air resistance. We also found out that the less area something has, the quicker it will take to fall.
I learnt a lot of interesting things that I didn't know about with how things fly and I hope I can learn more about them in the future.
