Impulse = Ft

From Newton's second law:

$\begin{array}{rcl}\mathbf{F}& \mathbf{=}& \mathbf{m}\mathbf{a}\\ & \mathbf{=}& \mathbf{m}\mathbf{\u2206}\mathbf{v}\mathbf{/}\mathbf{t}\\ \mathbf{F}\mathbf{t}& \mathbf{=}& \mathbf{m}\mathbf{\u2206}\mathbf{v}\end{array}$

It is correct to say that impulse is equal to

A. momentum.

B. the change in momentum.

C. the force multiplied by the distance the force acts.

D. all of the above

E. none of the above
