Speed at some instant, or assumed constant during a very short period of time, is called instantaneous speed. By looking at a speedometer, one can read the instantaneous speed of a car at any instant.
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.
