AIIMS2014PhysicsCenter of Mass, Momentum and Collision
Assertion: A quick collision between two bodies is more violent than a slow collision, even when the initial and the final velocities are identical. Reason: The rate of change of momentum is greater in the first case.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- DIf both assertion and reason are false.
Correct answer
A. If both assertion and reason are true and reason is the correct explanation of assertion.
Step-by-step solution
As p=m v, p v , and F= p t the rate of change of momentum is greater in a quicker collision between two bodies. The quicker collision between two bodies is more violent due to greater force.
