Front

Define potential energy.

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is the principle of conservation of energy?

Back

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