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.
No. The average speed is the average of the magnitude of the  velocity but not the magnitude of the average of the velocity.    This is because for vectors |A +  B| â¦ |A| + |B|.    Suppose you travel 100 metres due East at 10 metres per second and  then 100 metres due North also at 10 metres per second.
