1. Kinetic energy is the energy of motion.
2. Potential energy is stored energy.
3. The formula for kinetic energy is KE = 1/2 mv².
4. The formula for gravitational potential energy is PE = mgh.
5. Mass is measured in kilograms (kg).
6. Velocity is measured in meters per second (m/s).
7. Height is measured in meters (m).
8. Gravitational acceleration (g) is approximately 9.8 m/s².
9. The unit of energy is the joule (J).
10. Doubling the mass doubles the kinetic energy.
11. Doubling the velocity quadruples the kinetic energy.
12. Doubling the height doubles the potential energy.
13. A moving car has kinetic energy.
14. A book on a shelf has potential energy.
15. A roller coaster at the top of a hill has potential energy.
16. A roller coaster going down the hill has kinetic energy.
17. Energy cannot be created or destroyed, only transformed.
18. When a ball is thrown upward, kinetic energy converts to potential energy.
19. When a ball falls, potential energy converts to kinetic energy.
20. Friction converts mechanical energy into thermal energy.
