Which of the following correctly describes the unit Joule?

The unit Joule is defined as a measure of energy. It quantifies the amount of work done when a force of one newton moves an object one meter in the direction of the force. In the context of energy, the Joule is used to describe various forms of energy, including kinetic energy, potential energy, and thermal energy. Understanding the Joule as a unit of energy is fundamental in physics and various fields of science, as it allows for the calculation and expression of energy transfers and conversions in different systems.

For example, when electricity is used to heat up a substance, the energy transferred is often measured in Joules. This versatility is what makes the Joule an essential unit in scientific studies related to energy efficiency, thermodynamics, and mechanics.
