Motion is:

• Distance traveled in a period of time

• Energy of motion

• A change in position relative to a reference point

• Speed with a direction of motion

Energy cannot be created or destroyed, it just changes form:

• Law of conservation of energy

• Kinetic Energy

• Potential Energy

• Velocity
