Impulse Calculator

If you want to determine the object that changes its momentum over time, then you can use our impulse calculator.

In Physics, the impulse is used to determine a variation that occurred in an object due to its momentum. In other words, impulse can be defined as the substantial force applied to an object in a precise interval of time. In mathematical form, A product of force (F) and a change of the time (Δt) acting on an object is known as an impulse. The SI unit to represent the impulse is Newton-seconds which is equivalent to kg·m/s.


Formula of Impulse Calculator

To know how to calculate impulse manually, you can use the formula listed below; or, the find it instantly, you can jump to our calculator.

J = F.Δt

The above equation is driven by momentum, using the simple calculation listed below:

As we know, the formula of momentum is

p = m.v

Where a change in momentum will be equivalent to

Δp = m.Δv
Δp = m.a.Δt ; (Δv = a.Δt)
Δp = F.Δt ; (F = m.a)


J = Impulse (equivalent to ΔP=change in momentum)

F = Force applied on an object.

Δt = Change in time (Final time - Initial time)


To know more about it, you can use our Impulse Definition.


To understand the concept of impulse precisely, let us have an example below:

Suppose an object hit another object with a force of 48N, whereas the time interval between hitting an object is 4s, find out the impulse of an object.

Given data

F = force = 48N
Δt = time interval = 4s

To Find

The impulse of an object = ?


To find out the impulse of an object, we will use the formula listed below:

J = F.Δt

Putting values in the formula:

J = (48N).(4s) = 192 N.s
