Explanation:

  • Momentum is conserved in all collisions.
  • In elastic collision, kinetic energy is also conserved.
  • In inelastic collision, kinetic energy is not conserved. In perfectly inelastic collision, objects stick together after collision.
  • Hence, In inelastic collision of two particles total linear momentum only is conserved.

Perfectly elastic collision:

If law of conservation of momentum and that of kinetic energy hold good during the collision.

Inelastic collision:

If law of conservation of momentum holds good during collision while that of kinetic energy is not.

Coefficient of restitution (e)

  • For perfectly elastic collision, e = 1
  • For inelastic collision, e < 1
  • For perfectly inelastic collision, e = 0
