Energy is the capacity or ability to do work, which can manifest in various forms such as kinetic, potential, thermal, chemical, and electrical energy. It is a fundamental concept in physics and is essential for the functioning of matter and the universe. Energy can be transformed from one form to another but cannot be created or destroyed, a principle known as the law of conservation of energy. In everyday life, energy is utilized to power machines, heat spaces, fuel vehicles, and sustain biological processes. It is measured in joules (J) in the International System of Units (SI). Different sources of energy, such as fossil fuels, renewable energy (like solar and wind), and nuclear power, are used to generate electricity and provide heat. The study of energy involves understanding its sources, conservation, transformation, and its impact on the environment and society.
