When the bullet pierces a wooden block and stops, kinetic energy of the bullet gets converted into heat. Due to this, the temperature of the wood and the surrounding layers of wood increases. Temperature is related to the energy of the internal motion of the bullet not to the motion of the bullet as a whole.
