NEET Physics Impulse & Momentum MCQ Question
Which of the following combinations correctly describe the relationship between impulse, momentum, and forces acting on bodies during a collision?
Impulse is equal to the change in momentum of the object; the total momentum of an isolated system remains constant.
Impulse is the product of mass and velocity; it is always negative during a collision.
The force exerted during a collision is always greater than the impulse experienced by the object.
Impulse is a measure of the average force acting over a long time interval; momentum can change even with no net external force.
Correct Answer
Detailed Explanation
Impulse is defined as the change in momentum, and in an isolated system, the total momentum is conserved as stated in the context. The other options either misrepresent the definitions or contradict the principles of momentum conservation.
