This Average Velocity instructional video also includes:
You've launched a pumpkin into the air. How can you calculate its average velocity? Viewers learn how to calculate the average velocity of an object from tables and graphs, including a careful derivation of units, in the first installment of a 13-part video series. The video then connects the idea of average velocity to the slope of the secant line.
