A joule (J) is the standard unit of energy in the International System of Units (SI). It is used to measure various forms of energy, including mechanical, electrical, and thermal energy.
One joule is equivalent to the energy transferred or expended when a force of one newton is applied over a distance of one meter in the direction of the force’s application.
Joules are widely used in physics and engineering to quantify energy changes in physical systems, making them a fundamental unit for understanding energy-related concepts and calculations.
