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.
