Category: Energy

Energy is the capacity to perform work or produce change. It exists in various forms, including kinetic (movement), potential (stored), thermal (heat), chemical (from molecular bonds), electrical (from charged particles), nuclear (from atomic nuclei), and radiant (light). Energy can be transformed from one form to another but cannot be created or destroyed, as stated by the principle of conservation of energy. In physical systems, energy is often measured in joules or calories. It plays a crucial role in all natural processes and human activities, from powering machines to fueling biological functions. Energy is fundamental to the laws of physics and is essential for understanding the behavior of matter and systems in the universe.
