Work, energy, and power are fundamental concepts in physics that interrelate with one another. Work is defined as the energy transfer that occurs when an object is displaced by an applied force, measured in joules. Power is the rate of work done over time, while the work-energy theorem connects the work done on an object to its change in kinetic energy. The principles of conservation of energy dictate that energy cannot be created or destroyed, only transformed, affecting all physical systems.

Work is done when a force causes displacement in the direction of the force.
Energy is the capacity to do work and exists in various forms, such as kinetic and potential energy.
Power is the rate at which work or energy is transferred, measured in watts.
The energy transfer that occurs when a force acts on an object, causing it to move.
The capacity to do work, existing in forms such as kinetic and potential energy.
The rate at which work is done or energy is transferred, expressed in watts.
The principle stating that the work done on an object equals the change in its kinetic energy.
The law stating that energy cannot be created or destroyed, only transformed or transferred.
