Question

Momentum is most closely related to :

• A. force
• B. impulse
• C. KE
• D. power

Answer 1

Answer: (B)

impulse

Force is defined as the rate of change of momentum.

It is given by $\frac{\text{change of momentum}}{time}$.

Impulse is defined as the change of momentum. It is given by $Force\times time$.

Kinetic energy is the energy possessed by an object because of its motion. It is given by $\frac{1}{2}m{v}^2$. It can't be calculated by momentum alone. Power is the rate of work done with respect to time. it is not related to momentum.

Among force and impulse, There is a lesser calculation for impulse. Also, it has same dimensions as momentum. Hence that is most closely related.
