Work Done by Gravity

Work Done by Gravity

### Formula

$$W_g=mg(h_1-h_2)$$

### Terminologies

- Wg → Work done by gravitational force.

- m → Mass.

- g → Acceleration due to gravity.

- h₁ → Initial height.

- h₂ → Final height.

### Conditions / Special Cases

For downward motion:

$$W_g=mgh$$

For upward motion:

$$W_g=-mgh$$

### Usage

- Used in gravitational potential energy calculations.
