Question

Show that kg-m/s and N-s represent the same quantity Which is
that quantity?

Dear Student

Unit of linear momentum is kg -m/s and unit of impulse is N-S
Impulse (I) is defined as the force acting on an object for a
very short duration of time
The Impulse Momentum theorem relates the above two physical
quantities and is a fundamental theorem in mechanics
It simply states that an impulsive force acting on a body tends
to change its momentum by some amount
So we have

I = change in momentum = dp

I = F t

F t = dp
N s = Kg- m/s

So both units represent impulse
