CBSE Class 11: Work, Energy & Power - Perfectly Elastic Collision

May 19, 2015 16:37 IST

    In this video we will learn about the perfectly elastic collision.

    • For perfectly elastic collision:
      a) The coefficient of restitution is 1
      b) It follows the law of conservation of Linear momentum
      c) The kinetic energy remains conserved
      d) Total energy also remains conserved
    • The relation between velocity of approach and the velocity of separation for perfectly elastic collision, this approach is used to solve numerical like:
      a) How much the energy will be transferred from one body to another body during the perfectly elastic collision?
      b) What percentage of kinetic energy is retained by the first body
    • If the masses of bodies are identical, then the velocities will interchange.
      a) v1 = u2 and v2 = u1
