The following questions will review potential energy and kinetic energy calculations.

Multiple Choice

What is the correct unit for energy?

• meters (m)

• kilogram meters per second (kg m/s)

• Newtons (N)

Multiple Choice

The law of conservation of energy states

• Every action has an equal and opposite reaction

• Energy cannot be created or destroyed, it can only transform from one form to another

• Force = Mass x Acceleration

• Objects in motion remain in motion until a force acts upon. Objects at rest stay at rest until a force acts upon it.
