Question

For inelastic collision between two spherical rigid bodies,

• A. The total kinetic energy is conserved
• B. The total mechanical energy is not conserved
• C. The linear momentum is not conserved
• D. The linear momentum is conserved

Answer 1

The correct option is D

The linear momentum is conserved

1. In the absence of any external force, the total linear momentum will be conserved.
2. Since the inelastic collision has no external force, therefore, for an inelastic collision between two spherical rigid bodies, the total linear momentum will be conserved.

Hence, the correct option is$\text{'}D\text{'}$.
