Question
Define Energy
Answers
GPT-4o mini
Energy is a fundamental physical quantity that represents the capacity to perform work or produce change. It exists in various forms, including kinetic energy (the energy of motion), potential energy (stored energy based on an object's position or configuration), thermal energy (related to temperature and heat), chemical energy (stored in the bonds of chemical compounds), and many others such as electromagnetic energy, nuclear energy, and mechanical energy.
Energy can be transformed from one form to another but cannot be created or destroyed, a principle known as the conservation of energy. The standard unit of energy in the International System of Units (SI) is the joule (J), though other units like calories, kilowatt-hours, and electronvolts are also employed in different contexts. Energy plays a crucial role in all physical processes and systems, making it a central concept in physics, chemistry, biology, and engineering.
