# Force and Motion Age 10-12: Concept 2 - Force and Power: Unit 2

How do Tour de France bicycle racers improve their aerodynamics, the way the air pushes against them, in order to go faster? How do Olympic gymnasts put their bodies intentionally off-balance in order to create motion? How do skateboarders defy gravity to do tricks in the air? In this unit, you will explore the laws of physics that affect life on Earth, specifically how they affect people’s performance, from famous athletes to you and your friends, as you do individual sports.
