    Perfectly inelastic collision - conceptual - where does the lost KE go?

    Thanks Mapes, that conceptually makes a lot more sense. If energy is absorbed by the mass due to the resistance against deformation (the [+/-]acceleration of the mass to its v') during the collision and then radiated out as heat, then conservation of energy is maintained. Mathematically...

    Perfectly inelastic collision - conceptual - where does the lost KE go?

    you know, i have the same question myself. Mathematically, if you know the masses and the initial and final velocities of two objects before a collision, you will conserve momentum but not energy? To me the idea of heat being lost to friction doesn't make any sense, as we do not include mu, or...
