Instantaneous and Average Velocity. 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.
Full Answer. The instantaneous speed of an object should not be confused with the average speed. For example, a person who drives 60 miles in a single hour has an average speed of 60 miles per hour, but the instantaneous speed of the vehicle could vary greatly from one instant to another.
