Physics Form 4: Chapter 2 - Momentum

  • 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.
