Work-Energy Theorem

Work-Energy Theorem

### Formula

$$W_{net}=\Delta K$$

### Expanded Form

$$W_{net}=\frac{1}{2}mv^2-\frac{1}{2}mu^2$$

### Terminologies

- Wnet → Net work done.

- ΔK → Change in kinetic energy.

- u → Initial velocity.

- v → Final velocity.

### Conditions / Special Cases

- Valid for all types of forces.

- Net work determines change in kinetic energy.

### Usage

- Used to solve problems without finding acceleration.
