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

Answer» Solution :Inelastie collision : In 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 ITIS called s inelastic collision i.e., `"Total kinetic before collision "ne " Total energy after collision"` `({:(,"Total kinetic energy before collision"),(,"Total kinetic energy after collision"):})-({:(,"Total kinetic energy"),(,"after colision"):})=({:(,"loss in energy during collision"),(,"during collision"):})=triangleQ` Even though kinetic energy is not conserved but the total energy is conserved. This is because the total energy CONTAINS the kinetic energy term and also a term`triangleQ`, which includes all losses that take place during collision. Note that loss in kinetic energy during collision transformed to another form of energy like sound, thermal, el. Further, if the two colliding bodies stick together after collision such collisions are known as COMPLETELY inelastic collision or perfectly inelastie collision such a collision is found very often. For example when a CLAY putty is thrown on a moving vehicle, the clay putty for ( or Bubblegum) STICKS the moving vehicle and they move together with the same velocity.
