Impact of collision

(a) During impact of each of the colliding bodies experiences a dtrong force. Therefore, during the period of impact each of the bodies changes its momentum, but as a whole, the total momentum of the system does not change.


(b) Impact is practically followed by emission of light, sound, heat etc. Tehrefore, during an impact or collision, the mechanical energy of thesystem does not remain constant whereas the total energy of the system remains unchanged.


(c) In ideal case of collision such as collision between gas molecules, atoms, electrons, protons etc, the K.E of the system of colliding particles remains constant before and after the impact.


(d) In some collisions, the K.E of the system changes. In this case we cannot term the collision as perfectly elastic.


(e)For perfectly elastic collision, the K.E of the system at the begining and at the end of the impact must remain constant, but not during the impact.
