Potential energy is present in the river water behind a dam.
<h3>How is potential energy defined?</h3>
- Potential energy is a form of stored energy that is dependent on the relationship between different system components.
- When a spring is compressed or stretched, its potential energy increases.
- If a steel ball is raised above the ground as opposed to falling to the ground, it has more potential energy.
- The object's mass, its mass in relation to some reference points, and the gravitational field it is in all affect the potential energy of the object.
- Joule is the SI unit of potential energy as a result (J)
- As weight and height increase, gravitational potential energy rises.
