Multiple Choice

What is the difference between potential energy and kinetic energy?

Potential energy is the energy of an object due to an applied force, while kinetic energy is energy stored after the applied force.

Potential energy is the energy of an object due to its motion, while kinetic energy is energy due to its position.

Potential energy is the energy stored after an applied force, while kinetic energy is the energy used from the applied force.

Potential energy is the energy of an object due to its position, while kinetic energy is energy due to its motion.
