1. This power point is about forces and air resistance By Owen

2. What is air resistance  Air resistance, also called drag, is the forces that are in the opposition to the relative motion of an object through the air.  Children can experience air resistance by trying to run with open umbrellas held horizontally.  The faster an object is falling through air, the greater the air resistance.

3. Here is some facts about air resistance  1. The air resistance comes in up direction when it acts on the falling object. The gravity will push the object down, but the air resistance pushes the object up.  2. The air resistance is affected 2 factors. Both are shape and size. If the surface area is bigger, the air resistance is also bigger
