Energy is a fundamental concept in physics that refers to the capacity to do work or produce change. It exists in various forms, including kinetic energy (the energy of motion), potential energy (stored energy based on position), thermal energy (related to temperature), chemical energy (stored in bonds of chemical compounds), and many others. Energy can be converted from one form to another but cannot be created or destroyed, a principle known as the conservation of energy. It is a scalar quantity, measured in joules (J) in the International System of Units (SI). The concept of energy is crucial in understanding physical processes across all scales, from subatomic particles to large systems, and is key to fields such as thermodynamics, mechanics, and electromagnetism.
