If losses to heat and deformation are much smaller than the other energies involved, such as when two pool balls collide and go their separate ways, you can generally ignore the losses and say that kinetic energy was conserved. Most of the collisions in daily life are inelastic in nature. Basically, there are two main types of collision, elastic collision, and inelastic collision. In these situations, the original kinetic energy is sometimes lost in the form of heat or sound, both of which are the results of the vibration of atoms at the point of collision.
