What is inelastic collision ? In which way it is different from elastic collision. Mention few examples in day to life for inelastic collision.

Explanation

(i) In a collision, the total initial kinetic energy of the bodies (before collision) is not equal to the total final kinetic energy of the bodies (after collision) then, it is called as inelastic collision.
(ii) Mpmentum is conserved. Kinetic energy is not conserved in inelastic collision. Mechanical energy is dissipated into heat, light, sound, etc. When a light body collides against any massive body at rest it sticks to it.
(iii) Total kinetic energy before collision `ne` Total kinetic energy after collision. Total kinetic energy before collision - Total kinetic energy after collision = loss in energy during collision `= Delta Q`.
(iv) Even though kinetic energy is not conserved but the total energy is conserved.
(v) Loss in kinetic energy during collision is transformed to another form of energy like sound, thermal, etc.
(vi) If the two colliding bodies stick together after collision such collisions are known as completely inelastic collision or perfectly inelastic collision.
(vii) For example when a clay putty is thrown on a moving vehicle, the clay putty (or Bubblegum) sticks to the moving vehicle and they move together with the same velocity.
