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.
Beauty criterion (Dirac) The idea that the more aesthetically pleasant a theory is, the better it is. Of course this criterion does not stand up to the real test whether or no
