Energy of Satellite

Energy of Satellite

### Kinetic Energy

$$K=\frac{GMm}{2r}$$

### Potential Energy

$$U=-\frac{GMm}{r}$$

### Total Energy

$$E=-\frac{GMm}{2r}$$

### Terminologies

- r → Orbital radius.

- M → Mass of central body.

- m → Mass of satellite.

### Conditions / Special Cases

Total energy of a bound satellite is always negative.

$$E<0$$

### Usage

- Used in satellite energy calculations.
