Impulse

In classical mechanics, an impulse changes the momentum of an object. An impulse is calculated as the integral of force with respect to duration.

<math>\mathbf{I} = \int \mathbf{F} dt </math>

Using the definition of force yields:

<math>\mathbf{I} = \int \frac{d\mathbf{p}}{dt} dt </math>

<math>\mathbf{I} = \int d\mathbf{p} </math>

<math>\mathbf{I} = \Delta \mathbf{p} </math>
