Question

Impulse is ______.

• A. Scalar
• B. Equal to change in the momentum of a body
• C. Equal to rate of change of momentum of a body
• D. Force

Answer 1

The correct option is B

Equal to change in the momentum of a body

1. Impulse: Impulse is the integral of a force $F$ over time
2. ⇒ $F=m\frac{dv}{dt}$
3. ⇒ Impulse $Fdt=m\frac{dv}{dt}dt$
4. ⇒ Impulse $Fdt=mdv$, that is impulse = change in momentum
5. From the above derivation, it is clear that impulse = change in momentum of a body

Hence, option B is correct
