2. Kinetic Energy

​

Two Types of Energy

Three Types:

1. Gravitational Potential Energy

2. Chemical Potential Energy

3. Elastic Potential Energy

​

Potential Energy

1. Elastic Potential Energy - is energy stored as a result of applying a force to deform an elastic object.

2. Gravitational Potential Energy - is energy an object possesses because of its position in a gravitational field. (Depends on mass and height)

3. Chemical Potential Energy - is energy stored in the chemical bonds between atoms and molecules.
