2. WHAT IS ENERGY?

3. What is energy? Energy is defined as the ability to do work
It is measured in joules (J)

5. Energy can be classified as potential or kinetic
Potential energy: energy of position or also known as energy of rest

6. Potential energy can be classified as gravitational or elastic
Gravitational potential energy: energy of position above Earth’s surface A B C

8. When work is done to stretch something, it is called elastic potential energy.

9. Kinetic and potential energy convert to one anotherB

11. What is kinetic energy?
Energy of motion

12. What two variables affect kinetic energy?
Mass: the more mass an object has, the more kinetic energy
Velocity: the faster an object is moving the more kinetic energy it will have

13. FORMS OF ENERGY
When you place your pencil into the sharpener what happens? What do you see, hear, feel and maybe even smell?
What causes all of this to happen?

14. What are some types of energy?
Mechanical: motion of an object
Nuclear: stored in an atom and released during a nuclear reaction. Two types are fission and fusion
Electrical: moving electric charges
Thermal: the total movement of particles in an object (Temperature)
Electromagnetic: travels in waves
Chemical: stored in chemical bonds

15. The Law of Conservation of Energy
Energy can neither be created or destroyed……..just transferred

16. What type of energy are we running out of?

19. Nuclear energy- clean power for the world?...... “OR”

21. KABOOM!
