what is enegy

In physics, energy is the quantitative property that is transferred to a body or a physical system, recognizable in the performance of work and in the form of heat and light. It is the ability to do work and can exist in various forms such as potential or kinetic energy, thermal energy, electrical energy, and more. The concept of energy is essential for understanding the behavior of the physical world and is governed by the law of conservation of energy, which states that energy can neither be created nor destroyed, only changed from one form to another
