Newton’s Second Law
The relationship between Impulse and Newton’s Law of Motion is very crucial. Newton’s second law is very useful for finding the value of the Impulse.
We know that force acting on an object is given using,
F = ma
We know that acceleration (a = △v/△t)
F = m(△v/△t)
F△t = m△v
F△t = m(vf − vi)
where the quantity F△t implies that Impulse acting on the body and it is given as the change in linear momentum of the body.
This concept can be explained using the case of collision. In case of a collision large force is applied to a body if we reduce the time for the impact of the collision the impulse acting on the body is reduced drastically and thus the impact of the collision is lower.

What is Impulse?
Impulse in Physics is defined as the force acting on the body for a very shorter period of time. It is the instant change in the momentum of the body. For example, in case of collision, the instant change in the momentum of the body just before and after the collision is called the Impulse acting on the body.
The damage sustained by the body is dependent on the impulse applied to the body. It is denoted using the letter ‘J’ and is calculated by taking the product of the force applied and the time for which the force is applied.
In this article, we will discuss the concept of Impulse, its formula, equations, and others in detail in this article.
