Potential Energy

Potential Energy

Potential energy is the energy possessed by an object due to its position or configuration.

### Formula

$$U=mgh$$

### Terminologies

- U → Potential energy.

- m → Mass.

- g → Acceleration due to gravity.

- h → Height from reference level.

### SI Unit

$$Joule$$

### Dimensions

$$[U]=[ML^2T^{-2}]$$

### Conditions / Special Cases

- Reference level for potential energy can be chosen arbitrarily.

- Only change in potential energy has physical significance.

### Usage

- Used in gravitational energy problems.
