Force, work, energy, and power are fundamental concepts in physics that describe interactions and transformations in the physical world. Force is a push or pull that can cause an object to move, stop, or change direction. When a force moves an object over a distance, work is done, transferring energy to the object. Energy, the capacity to do work, can exist in various forms like kinetic or potential. Power measures the rate at which work is done or energy is transferred, reflecting how quickly these processes occur. Together, these concepts explain how objects interact, move, and change within their environments.
