NEET Physics Impulse & Momentum MCQ Question
Which of the following statements about impulse and momentum is correct?
Impulse is equal to the change in momentum, regardless of the duration of the force applied.
A smaller force acting over a longer duration can produce the same impulse as a larger force over a shorter duration.
Momentum is always conserved in systems where external forces are present.
Impulse can be calculated as the product of mass and velocity of an object at any time.
Correct Answer
Detailed Explanation
Impulse is defined as the product of force and time duration, which results in a change in momentum. A larger force for a short time can produce the same impulse as a smaller force for a longer time, supporting option B. The conservation of momentum only holds in isolated systems, making option C incorrect.
