If and only if the acceleration is constant the average velocity is the same as the average of the final velocity and the initial velocity. The average velocity during the acceleration can be found using the formula. However there is a difference between speed and velocity.
Average velocity is a vector quantity.
However there is a difference between speed and velocity. V average velocity. The D is a mathematical symbol which means change in You can express average velocity as either a v with a horizontal bar over it or vav. Created by Sal Khan.
