Question

In an inelastic collision, what is conserved

• A. Kinetic energy
• B. Momentum
• C. Both (a) and (b)
• D. Neither (a) and (b)

Answer 1

The correct option is B

Momentum

1. An inelastic collision occurs when there is a loss of kinetic energy.
2. While the system's momentum is maintained in an inelastic collision, kinetic energy is not.
3. This is due to the transfer of some kinetic energy to something else.
4. In a ballistic pendulum, an inelastic collision occurs.
5. Newton's second law of motion states that the rate of change of momentum is equal to the applied force on the system.
6. If we consider the two colliding bodies to be a system, there is no external force, hence momentum must be conserved because the rate of change of momentum is zero.

Hence, correct option is (b) Momentum.
