Question asks us about elastic collisions.
00:04
Elastic collisions.
00:05
So what happens in elastic collisions is, what happens with kinetic energy, kinetic energy and momentum in the elastic collisions.
00:17
So considering the momentum first, the momentum is conserved, that is conservation of momentum is observed.
00:27
Conservation of momentum is observed in elastic collisions.
00:33
How? because in any case, in any case whether the collision is elastic or not, the total momentum before the collision is equals to the total momentum after the collision.
00:51
That is initial momentum is equals to the final momentum.
00:57
Hence it means that the sum of momenta, the sum of momenta of all the objects, of all the objects involved in the collision remains constant...
