4 Forces of Planes

1.  Thurst
2. Gravity
3. Lift
4. Drag 

Challenge: To fine a paper plane that beats the rest of the class.

Aim: I want to find a paper plane that beats the rest of the class.

Thrust pushes the plane forward.

Lift pushes the plane up.

Gravity (or weight) pulls the plane down.

Drag pushes the plane backwards.

How can you change the forces from above to make the airplane go further? 

• Need to increase the thrust - to do this , I will throw harder.
• Reduced Drag.
• Change air flow - add ailerons.
