In a perfectly inelastic collision, what happens to kinetic energy?

Explanation:
In a perfectly inelastic collision, momentum is conserved but kinetic energy is not. When the objects collide and stick together, some of the initial kinetic energy is transformed into other forms of energy—deformation of the bodies, heat, sound, and internal energy. This is why the final motion has less kinetic energy than the initial motion, even though the total momentum remains the same. So the kinetic energy is converted to other forms of energy.
