Instantaneous and Average Velocity

The instantaneous velocity of an object at a particular time is equal to the slope of its position vs. time graph at that time. On the other hand, the average velocity between two times is equal to the slope of the line joining the two points on the position vs. time graph. Run the applet to the right to make sure that you understand these two concepts -- both their similarities and differences. If you have trouble relating position vs. time graphs to actual motion, review the comparison between motion diagrams and graphs.
