Question: 1 / 400

What is the unit of energy?

Joule

The unit of energy is the Joule. This unit is defined in terms of the work done when a force of one newton acts over a distance of one meter. It can also be related to other forms of energy, such as heat, where one Joule is equivalent to the energy transferred when an electric current of one ampere passes through a resistance of one ohm for one second.

In contrast, the Watt is the unit of power, which measures the rate of energy transfer or conversion over time, specifically one Joule per second. The Pascal is the unit of pressure, defined as one newton per square meter, while the Newton is the unit of force. Each of these units serves a distinct purpose in the field of physics and engineering, highlighting the importance of correctly identifying the unit specifically associated with energy, which is the Joule.
