Pages

2. What is Energy? Energy is the ability to do Work or cause a change
Measured in Joules, like Work

3. Kinetic Energy Kinetic Energy is the energy of motion
All moving objects have Kinetic Energy (KE )
What determines an object’s KE?
Mass & Velocity determine the KE of an object.

4. Potential Energy Potential Energy (PE ) is stored energy
It has the potential or “possibility” to do work
Gravitational PE is energy that depends on height
Elastic PE is for objects that can be stretched.

5. Mechanical Energy
Energy associated with motion (KE & PE)

6. Thermal Energy
Energy of particles in an object

7. Chemical Energy
Energy stored in chemical bonds

8. Electrical Energy
Moving electric charges

9. Electromagnetic Energy
Waves of energy, such as light

10. Nuclear Energy
The fusion or fission of atoms

11. Which of the following is an example of Kinetic Energy?
Compacted spring A
Boulder atop a mountain B
Boulder rolling down a mtn. C
Bike at the top of half pipe D

12. A bow string that is pulled back and ready to fire is…
Gravitational PE A
Elastic PE B
Rubber KE C
Elastic KE D

13. Exit Pass
What is the difference between Kinetic and Potential energy? Give an example of each.
