- Momentum is defined as the product of mass and velocity.

- The principle of conservation of momentum states that in a system of collision or explosion, the total momentum is constant if
**no external force**is acted upon the system.

Total Momentum Before Reaction = Total Momentum After Reaction

**Elastic collision**is the collision where the kinetic energy is conserved after the collision.**Inelastic collision**is the collision where the kinetic energy is not conserved after the collision.
