Question

ASSERTION: Impulsive force is large and acts for a short time.
REASON: Finite Change in momentum should be produced by the force.
A) Both assertion and reason are correct and reason is the correct explanation for assertion.
B) Both assertion and reason are correct but the reason is not the correct explanation for assertion.
C) Assertion is correct but reason is incorrect.
D) Both assertion and reason are incorrect.

Answer 1

Hint: Change in momentum is force times acting time. Forces which work for a short amount of time are known as impulses. The instinct is the product of impulsive strength and the moment it acts. The pulse refers to the momentum shift caused by the impulse

Complete step by step solution:
In classical mechanics, the momentum is the central component of the force that operates over the time interval. As force is a number of vectors, impulse is also a quantity of vectors. The impulses applied to an object produce a vector transition counterpart, both in the form of its linear momentum.
In the above given question,
We know that Impulse is defined as a product of force and time or we can say that impulse is also known as change in momentum.
Therefore, a large force acting for a short time to produce a finite change in momentum is called an impulsive force.

Hence, Both assertion and reason are correct and reason is the correct explanation for assertion.

Note: Momentum is mass in motion, and any object that moves can have momentum. The shift of momentum of an object is the same as its momentum. Impulse is the number of strength times the time interval. The momentum itself is not the same, it is the growth or the decrease in the momentum of an object.
