Average Speed and Average Velocity: Formula, Definition ...
Average velocity = vavg = (bar over v means ‘average’). Example: In the above example, assume that it took 3 s to go 10 m east and 2 s to come back 3 m west. Then (+sign means direction of v is east.) Average speed = Instantaneous velocity is the average velocity determined for an infinitesimally short time interval:

Lesson 1
The average velocity over an interval is. The change in average velocity should be related to the acceleration in a fairly straightforward manner. With a series of substitutions, we have. Using the first and last line of the expressions above, a can be expressed in terms of the quantities that will be measured: ...

Find the ball’s displacement over the time interval from t = 2s to t = 5s. Solution: If we looked at the graph and found that the ball was located at x = 4m at t=2 s and x = 1 m and t = 5s, then the answer would be. 3. Average Velocity – The average velocity is found by using the definition of average velocity:.
velocity formulas

Activity overview:
If its average velocity is zero, then the displacement must be zero over the time interval, according to Equation 2.2. The object might be stationary throughout the interval. If it is moving to the right at first, it must later move to the left to return to its starting point. Its velocity must be zero as it turns around.
