1. Potential and Kinetic Energy

2. How is all energy divided?
Potential
Energy-PE
Kinetic
Energy-KE
Gravitation
Potential
Energy (GPE)
Elastic
Energy
(EPE)
Chemical
Energy (CPE)

3. What is Potential Energy?
Energy that is stored and waiting to be used later

4. What is Gravitational Potential Energy?
Potential energy due to an object’s position
P.E. = weight x
height
Don’t look down, Rover!
Good boy!

5. What is Elastic Potential Energy?
Potential energy due compression or expansion of an elastic object.
Notice the ball compressing
and expanding

6. What is Chemical Potential Energy?
Potential energy stored within the chemical bonds of an object

7. What is Chemical Potential Energy?
Energy from the food we eat.

8. What is Kinetic Energy? Energy an object has due to its motion
K.E. = mass x velocity2 2

9. The Law of Conservation of Energy
What is a law in science?
What did you learn about how potential and kinetic energy change forms?
What conclusions can you draw?

10. What is Mechanical Energy?
The total energy of motion and position of an object. It is the amount of WORK an object can do because of its kinetic and potential energies.
Mechanical energy= potential + kinetic
