Energy is a fundamental concept in physics, representing the ability of a system to perform work or cause a change. It’s an essential quantity that exists in various forms and underlies virtually every aspect of the universe. Energy manifests in diverse ways, including kinetic energy related to motion, potential energy stored in positions or configurations, thermal energy within substances, and many others. This concept plays a pivotal role in describing and predicting the behavior of physical systems, from the movement of celestial bodies to the functioning of cells in living organisms. The law of conservation of energy, a foundational principle in physics, asserts that energy can neither be created nor destroyed, only transformed from one form to another. This principle is fundamental in understanding natural processes, technological advancements, and the interplay of energy across different fields, shaping our comprehension of the cosmos and powering innovations that shape our daily lives.
