# Impulse with Time

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Impulse, abbreviated as I, is a change in momentum of an mass when a force is applied over time.

## Impulse with Time formula

$$\large{ I = F \; \Delta t }$$
Symbol English Metric
$$\large{ I }$$ = impulse $$\large{\frac{lbf}{sec}}$$ $$\large{N-s}$$
$$\large{ F }$$ = force $$\large{lbf}$$ $$\large{N}$$
$$\large{ \Delta t }$$ = time differential $$\large{sec}$$ $$\large{s}$$
