Energy

Energy is the capacity to do work or to produce change, and it exists in various forms, such as kinetic, potential, thermal, chemical, electrical, and nuclear energy. In physics, energy is a conserved quantity; it can be transformed from one form to another but cannot be created or destroyed. Energy is fundamental in understanding the behavior of matter and the interactions within a system. It plays a critical role in all physical processes, from the movement of objects to the functioning of living organisms. In everyday life, energy powers everything from our homes and transportation systems to electronic devices and industrial machinery. The study of energy also encompasses concepts like efficiency, power, and energy transfer, which are crucial in fields ranging from engineering to environmental science.
