Impulse

Impulse is the transference of momentum (like how Work is the transference of energy):

\begin{align} impuse &= \int \vec{F} dt \\ &= \Delta \vec{\rho} \end{align}

It is very similar to the Work equation, and but it is instead integrating on change of Time.

Just in case you forgot:

\begin{equation} \vec{\rho} = m\vec{V} \end{equation}
