Work and energy are measured in the same units. Joule measures work and energy.
All human life depends on energy.
Joule by Ashley Joule is in the metric system. As you know Joule measures work and energy. One joule is the amount of work done when a force of one newton acts on an object that moves one meter in the direction of the force. The joule is used to measure all forms of energy, including heat, electrical, and mechanical energy. One joule per second is called a watt, a unit of electrical and mechanical power.
