Escape Energy

Escape Energy

### Formula

$$E=\frac{GMm}{R}$$

### Terminologies

- E → Minimum energy required to escape gravitational field.

- G → Universal gravitational constant.

- M → Mass of planet.

- m → Mass of object.

- R → Radius of planet.

### Conditions / Special Cases

Escape velocity:

$$v_e=\sqrt{\frac{2GM}{R}}$$

### Usage

- Used in satellite and gravitational energy problems.
