# Momentum Change in Velocity

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

This calculation determines the change in momentum when the velocity changes but the mass remains constant.

## Momentum Change in Velocity formula

 $$\large{ p = m \left( v_i - v_f \right) }$$

### Where:

$$\large{ p }$$ = momentum

$$\large{ m }$$ = mass

$$\large{ v_f }$$ = final velocity

$$\large{ v_i }$$ = initial velocity
