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.
Speed = Distance/Time. or. s = d/t. 1  Instantaneous Speed-The speed of an object at a given moment. 2  The car may be travelling at 50 mph at this moment, but it may slow down or speed up during the next hour. 3  Average Speed-The average speed is calculated by the distance that an object traveled over a given interval of time.r. s = d/t. 1  Instantaneous Speed-The speed of an object at a given moment. 2  The car may be travelling at 50 mph at this moment, but it may slow down or speed up during the next hour. 3  Average Speed-The average speed is calculated by the distance that an object traveled over a given interval of time.
