INELASTIC COLLISION:
"The collision in which total momentum is preserved but total K.E of system is not conserved is known as inelastic collision".
It is to be noted that momentum and total Energy are conserved in all types of collision. However K.E is conserved only in elastic collisions.
newton; N (after Sir I. Newton, 1642-1727) The derived SI unit of force, explained as the force needed to give a mass of 1 kg an acceleration of 1 m/s 2 ; thus it has units of
The waves which needs medium for their propagation are known as mechanical waves. Example : Waves on string and spring, waves on water surface, sound waves, seismic waves.
