What is the metric term for Energy?

The metric term for energy is the Joule. This unit is defined as the amount of energy transferred when one newton of force is applied over a distance of one meter. It is widely used in various fields such as physics, engineering, and any applications involving work and energy calculations.

The Joule is particularly important in the context of heavy-duty mechanics because it quantifies energy, work, and heat, making it essential for understanding how systems operate and for calculating efficiency and power requirements.

The other options represent different physical quantities: the Newton is a unit of force, the Watt is a unit of power (which is the rate of doing work or transferring energy), and the Pascal is a unit of pressure. Each of these units serves a different purpose in the metric system, but when it comes to energy specifically, the Joule is the appropriate and correct choice.
