AIIMS 2019 Physics Elastic and Inelastic Collisions Assertion Reason Question
Assertion: Collision between two billiard's ball are inelastic Reason: Momentum remains conserve during the collision
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
The assertion is true because collisions between billiard balls are typically elastic, meaning kinetic energy is conserved, not inelastic. The reason is false; while momentum is conserved in all types of collisions (elastic and inelastic), the statement incorrectly categorizes billiard ball collisions as inelastic. Option A is incorrect because the reason does not correctly explain the assertion. Option B is also incorrect since the assertion is not true. Option D is incorrect as the assertion is true. Understanding the distinction between elastic and inelastic collisions is crucial in physics, as it affects energy conservation during interactions.
