In an inelastic collision, Momentum is _ and Kinetic Energy is _ respectively.
Correct answer: B. conserved ; not conserved
- A. Not conserved ; not conserved
- B. conserved ; not conserved
- C. Conserved ; conserved
- D. Not conserved ; conserved
Explanation
For elastic and inelastic collisions, momentum and total energy are always conserved provided no external force is applied; however, for inelastic collisions, kinetic energy is NOT conserved.

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.
