Discovering Physics - Motocross is an exciting sport where motorcycles race around an off road circuit. The riders experience thrilling motion such as flying through the air and negotiating sharp turns. Speed, acceleration, and braking are some factors that challenge a rider's ability. How can knowledge of motion help riders complete the circuit?

Chapter Opener: Hypermiling - Concerns about the environment and rising fuel prices have led drivers to become increasingly aware of the consequences of their driving habits.

PowerPoint and SMART Notebook Lesson Supplements: Chapter 1 - Lesson supplements with regard to Chapter 1 - Constant velocity represents uniform motion.

Explore More - Mass and weight measure different quantities, but why is one scalar and one vector?

Take It Further - Understanding how biological systems move is a branch of physics known as biomechanics. For automobile manufacturers, understanding how the human body moves during a car accident is very important. Today, crash test dummies are used to study, collect, and analyze data on how the human body moves during a vehicular collision.
