Impulse Definition
When a net force acts on a body, it causes acceleration, which changes the body’s motion. A larger net force will result in greater acceleration than a small net force. If the big and tiny forces occur at different time periods, the overall change in motion of the item might be the same. The combination of force and time acts as a valuable quantity leading to the definition of impulse.
The product of the average net force acting on an item for a certain period of time is sometimes referred to as the impulse.
Impulse Formula
Impulse is a vector quantity and the formula for impulse is given using the formula,
J = F × Δt
where,
J is the impulse
Δt is the time interval
F is the force.
It’s worth noting that we assume force remains constant throughout time. Like force, the impulse is a vector quantity with a direction.
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.
