**Basics of Potential Energy**

**What is Potential Energy?**

Potential energy is the energy an object possesses due to its position or configuration relative to other objects. It comes in various forms, such as gravitational potential energy, elastic potential energy, and electric potential energy, and is measured in joules (J).

**The Nature of Potential Energy**

Potential energy is a scalar quantity, meaning it has magnitude but no direction. It represents energy stored within a system and is not dependent on the object’s motion.
