Question

Define impulse of a force. write it's mathematical expression and also the unit of impulse. ​

Answer 1

Answer:

1)The product of force and time that produces a finite change in momentum of the body is called impulse

2)Impulse(J)=Force×time

=(m.a)(t)

=m(v-u)

t

=m(v-u)

=mv-mu

:. Impulse(J)=Change in momentum

3)unit of impulse = Ns( newton second)
