Congress has often used the Commerce Clause to justify exercising legislative power over the activities of states and their citizens, leading to significant and ongoing controversy regarding the balance of power between the federal government and the states.
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.
To calculate the average velocity, we might take two points on the graph of. separated by a time interval and calculate the velocity. We note that. 1  At time, the ball has fallen by a distance. 2  A little later, at time, the ball has fallen by a distance. 3  The time between these two data points is, which we may think of as the time between strobe flashes. 4  Therefore, the average velocity between these two instants is:
