How and why do things move?

The lessons in this unit explore the basics of forces and motion.

Lesson 1 - Exploring Energy helps students explore the fundamental types of energy: potential and kinetic.
Lesson 2 - Friction Races gives students digital hands on experience on using potential and kinetic energy.
Lesson 3 - Centripetal Force helps older students explore other forces which affect movement.

All of these lessons together help us understand forces and motion. Enjoy the journey!
