One of two things: Either an elastic or inelastic collision

Explanation:

If the collision is perfectly elastic, meaning the two bodies hit and then move apart, both momentum and kinetic energy are conserved.

If collision is inelastic, meaning the objects stick together for a bit and then split apart or stick together entirely (a perfectly inelastic collision), momentum is conserved but kinetic energy is not
