## cp9454 10 months ago it is always true to state that speed is the magnitude of velocity. following the logic, can youdefine the average speed as magnitude of average velocity.

That's not quite correct logic. Since the average velocity can be zero because it is not always true that the components of velocity have to be greater than zero in a coordinate system.

That is, consider a car that takes a path from point A to point B and back to point A (where point A and B are some distance $$s$$ away). Then, the car has an average velocity of zero (as it is back to its starting point), yet the car's speed is $$\frac{2s}{t}>0$$.
