Final answer:
Potential energy is the energy held by an object due to its position or charge, while kinetic energy is the energy of an object in motion. Work is the transfer of energy by a force, and power is the rate at which energy is used.
Step-by-step explanation:
Potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, or its electric charge. Kinetic energy is the energy of an object in motion. Work is the transfer of energy to or from a system by a force that acts on it. Power is the rate at which we use energy.
