Q. Impulse is
A) A scalar
B) Equal to change in the momentum of a body
C) Equal to rate of change of momentum of a body
D) A force
Explanation
(b) Impulse is given by the product of force and time. Form Newton’s second law
$F = ma = m\frac{\mathrm{\Delta}v}{\mathrm{\Delta}t}$
$\Longrightarrow \ \ F\mathrm{\Delta}t = m\mathrm{\Delta}v$
= change in the momentum of the body.
