NEET Physics Impulse & Momentum MCQ Question
Which of the following statements about impulse and momentum is correct?
Impulse is the product of force and the time duration over which it acts, resulting in a change in momentum.
A greater impulse results in a lesser change in momentum if the force is applied for a longer duration.
Momentum can only change if the acting force is constant in magnitude and direction.
Impulse and momentum are always in the same direction regardless of the force applied.
Correct Answer
Detailed Explanation
Impulse is defined as the product of force and the time duration during which the force acts, which equals the change in momentum, as stated in the NCERT context. The other statements reflect misconceptions about the relationship between force, time, impulse, and momentum.
