Air resistance

• Resistance blocks you from doing things like if there a thorny bush it's blocking you from getting a ball.

• Air resistance slows,stops and turns around like a air plane can not fly forever because air slows it down and eventually stops the paper plane from moving.

• And like a parachute air pushes it down but the longer it is the slower  it is because it is like landing on air so it slows down from falling.

• If some thing goes really far and it hits some thing you won't feel it because the air slowed it down so much.
