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.
Although average velocity is useful in describing the motion of an object over a certain time interval, it canât describe the motion of an object at an instant in time during the interval. For this, a new description on how to calculate velocity needs to be defined, called instantaneous velocity.
