1. Kinetic Energy -Energy that an object has because of its motion.
Key Terms:
Potential Energy - Stored energy that an object has be because of its position or chemical makeup.
Kinetic Energy -Energy that an object has because of its motion.
Energy – The ability to do work.

2. PE = mgh KE = (1/2)mv2 Key Formulas PE = Energy (in Joules)
m = mass (in kilograms)
g = gravitational acceleration of the earth (9.8 m/sec2)
h=height above earth’s surface (in meters)
KE = (1/2)mv2
KE = Energy (in Joules)
v = velocity (in meters/sec)

3. Key Law
The Law of Conservation of Energy
Energy in a system may take on various forms (e.g. kinetic, potential, heat, light). The law of conservation of energy states that energy may neither be created nor destroyed. Therefore energy is transformed from one type to another.

4. Brain Quiz
3) The law of conservation of energy states that when one form of energy is converted into another, a. energy is destroyed in the process. b. no energy is destroyed in the process. c. energy is created in the process. d. some amount of energy cannot be accounted for.

5. Key Concepts
Potential energy exists whenever an object which has mass has a position within a force field. The most everyday example of this is the position of objects in the earth's gravitational field. Kinetic Energy exists whenever an object which has mass is in motion with some velocity. Everything you see moving about has kinetic energy.

6. Kinetic Energy - What Is Energy?
Kinetic energy increases as mass and velocity increases.

7. Potential Energy - What Is Energy?
Gravitational potential energy increases as weight and height increase.
