The joule is a unit of energy, equal to the energy transferred to an object when a force of one newton acts on that object in the direction of its motion through a distance of one meter. It is also a unit of work, equal to the work done when an applied force of one newton moves an object through a distance of one meter in the direction of the force.
The Joule is a unit of energy in the International System of Units (SI). It is named after the British physicist James Prescott Joule, who established the principle of conservation of energy. One Joule is defined as the amount of energy expended when a force of one Newton is applied over a distance of one meter. This unit is used to express various forms of energy including mechanical, electrical, thermal, and chemical energy. It is used in a wide range of scientific and everyday applications such as determining the amount of work done by a force, calculating the amount of heat generated by an electrical resistor, and measuring the energy content of foods and fuels. Other commonly used energy units include the calorie, British thermal unit (BTU), and electronvolts (eV).
