Energy and Energy Transformation

What is the difference between potential energy and kinetic energy?

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

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

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