Front

Explain the difference between kinetic energy and potential energy.

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.
