Question

what is impulse of force? state it's formula and SI unit

Answer 1

the products of impulsive force and time for which it acts is called impulse

Answer 2

Impulse is the product of Force and Time. It's S.I. unit is kg-m/s.

Dimensional Formula :
Impulse=force*time

Force=mass*acceleration

MASS=[M]

ACCELERATION=[LT^-2]

SO FORCE=[MLT^-2]

TIME=[T]

So impulse comes out to be =[MLT^-2]×[T]

=[MLT^-1]

Hope this will help you...... ✌
