Question

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

Answer 1

Answer: (B)

Impulse is given by the product of force and time.
From Newton's second law
$F=ma=m\frac{\Delta V}{\Delta t}$
$\Rightarrow$ $F\Delta t=m\Delta V$
$=$ change in the momentum of the body.
