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.
The difference is speed does not depend on direction while velocity depends on direction. Speed is a scalar quantity while velocity is a vector quantity. Like this, if it is speed, you would just refer it to 2 m/s.If it is velocity, you refer it as this 2m/s east (with direction). So, average speed is the total distance taken over the total time taken (regardless of direction) while average velocity is the same whole thing, except it includes direction.ike this, if it is speed, you would just refer it to 2 m/s.
