Which one of he following is true in the case of inelastic collision?
Correct answer: B. B
- A. A
- B. B
- C. C
- D. D
Explanation
B is the correct option. Momentum and total energy are always conserved in elastic as well as inelastic reactions. As far as KE is concerned, it is not conserved in inelastic 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.
