Verify that the si unit of impulse is the same as the si unit of momentum.

Maybe this will help you out:

Momentum is calculate by the formula:

Where:

P = momentum

m = mass      

v = velocity

The SI unit:

So the unit of momentum would be:

Impulse is defined as the change in momentum or how much force changes momentum. It can be calculate with the formula:

I = FΔt

where:

I = impulse

F = Force

Δt = change in time

The SI unit:

F = Newtons (N) or

t = Seconds (s)

So the unit of impulse would be derived this way:

I = FΔt

I = x

or

You can then cancel out one s each from the numerator and denominator and you'll be left with:

So then:

Momentum:                             Impulse
