A bomb utilizes the potential energy which is in the form of chemical energy stored in the bomb.

It is important to note that even after the bomb explodes , the momentum doesnt change for the whole bomb as the explosion is caused by

internal force and no other external force acts on it .  So if before exploding bomb is at rest , the particles after explosion

will fly away in a diretion such that the sum of momentum of all particles is zero.
