\[v_{avg} = \frac{v_0 + v}{2}\]
Variables
vavgaverage velocity (m/s)
v0initial velocity (m/s)
vfinal velocity (m/s)
Description
What is this formula?
This formula calculates the average velocity of an object moving with constant acceleration between two velocity states.
When to use it
Use this equation when acceleration is constant and both the initial and final velocities are known.
Example
If a vehicle increases its velocity from 8 m/s to 20 m/s:
vavg = (8 + 20) / 2 = 14 m/s
Applications
Motion analysis, transportation engineering, mechanical systems, robotics, and introductory physics.
