When two bodies stick together after collision, the collision is said to be:
Correct answer: C. completely inelastic
- A. perfectly elastic
- B. partially elastic
- C. completely inelastic
- D. none of these
Explanation
When two bodies stick together after a collision, it's termed a completely inelastic collision. In this type of collision, kinetic energy is not conserved, and the maximum amount of mechanical energy is lost. The bodies move together as a single unit after the collision.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
