What makes some collisions elastic and others inelastic?
quester [9]

Answer : The The correct option is, If there is energy lost in the collision to sound, heat, etc., the collision is inelastic.


Explanation :

  • Elastic collision : It is defined as in which there is no loss of kinetic energy in the collision.
  • Inelastic collision : It is defined as in which there is a loss of kinetic energy in the collision and this energy changed to another form of energy.

If the collision involves bouncing, it is inelastic because kinetic energy is not conserved.

If the collision involves sticking together, it is inelastic because kinetic energy is not conserved, it is changes to potential energy.
