Does impulse equal momentum, or a change in momentum?
Whether the impulse is equal to the momentum or to the change in momentum.
Answer to Problem 7A
Impulse is equal to the change in momentum.
Explanation of Solution
Introduction:
When a force is applied on an object for some time, an impulse is transferred on it given by,
More the impulse on the object, more is the change in its momentum. Hence,
Where,
Conclusion:
As can be seen from above formula, the impulse on any object is equal to the change in the momentum of the object.
