Unit for potential energy

The unit for potential energy is the Joule.

The Joule (J) is the SI unit for energy, including potential energy. One Joule is defined as the amount of work done when a force of one Newton (N) displaces an object by one meter (m) in the direction of the force.

$$1 \text{ J} = 1 \text{ N} \cdot \text{m} = 1 \text{ kg} \cdot \text{m}^2/\text{s}^2$$

The unit for potential energy is $\text{Joule (J)}$.
