This power point is about forces and air resistance By Owen

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
