When two bodies collide and the bodies stick to each other after colliding they share their momentum and move as one?

let's put this straight. As two or more bodies collied, as they further stick together, there is a possibility of different kind of energy taking roles. for instance the total energy before hitting each other is let's say 10 joule. Now, let's take factors which may play role during the collision, for instance, surrounding medium(for instance, air) which may cause sound energy, bodies may deform which is likely to store a tiny fraction of potential energy, surface interaction may cause heat energy. Therefore, Sound energy(0.5 joule), heat energy(0.5joule) etc may dissipated in the surrounding. However the amount of energy dissipation totally depends on the surrounding and interactive factors such as medium, nature of surface, temperature of the medium, elasticity of interacting bodies.
