Complete inelastic collision

  1. May 17, 2015 #1
    Could be a stupid question. But in case of complete inelastic collision, when one particle is at rest and other one collides with it and both move together, I made calculations(pretty simple ones), the conservation of linear momentum and conservation of kinetic energy give different results.
    Can anyone explain it?

    They should, kinetic energy is only conserved in elastic collisions.

    So, what happens to rest of the energy? Heat? Any law of thermodynamic?

    Depends on the collision. Heat, internal energy, sound, etc.

    I mean there's a precise amount of energy getting drained. It has to impact somewhere, like if in space, sound won't be a concern. If you can tell it more specifically. But thanks anyway, I got it. A burden out of my head.
