Loss of Kinetic Energy in Inelastic Collision

Loss of Kinetic Energy in Inelastic Collision

### Formula

$$\Delta K=\frac{1}{2}\frac{m_1m_2}{m_1+m_2}(u_1-u_2)^2$$

### Terminologies

- ΔK → Loss of kinetic energy.

- u₁-u₂ → Relative velocity before collision.

### Conditions / Special Cases

For perfectly elastic collision:

$$\Delta K=0$$

### Usage

- Used to calculate energy loss during collision.
