# Average Force

Written by Jerry Ratzlaff. Posted in Fluid Mechanics

Average force is used when the velocity was not measured precisely.

## FORMULA

$$\bar F = m \frac { \left( v_f \;-\; v_i \right) } {t}$$

Where:

$$\bar F$$ = average force

$$m$$ = mass

$$v_f$$ = final velocity

$$v_i$$ = initial velocity

$$t$$ = time
