# Velocity Differential

Velocity differential is the average rate of change or displacement with time. This is determined by taking the instantaneous velocity of an object, relative to another, in two points of time. The calculator below, determines change of the average rate over these two points.

## Velocity Differential Formula\(\large{ \Delta v = v_f \;- \; v_i }\) Where: \(\large{ \Delta v }\) = velocity differential \(\large{ v_f }\) = final velocity \(\large{ v_i }\) = initial velocity |
