Question

Average speed can mean the magnitude of the average velocity vector. Another meaning given to its that average speed is the total length of path travelled divided by the elapsed time. Are these meaning different? If so, give an example​

Answer 1

Answer:

Average speed can mean the magnitude of the average velocity vector. Another meaning given to it is that the average speed is the total length of the path traversed divided by the elapsed time.

Answer 2

Explanation:

Average speed can mean the magnitude of the average velocity vector. Another meaning given to it is that the average speed is the total length of the path traversed divided by the elapsed time.

The meanings are different. The point can be made clear by considering the motion of a particle along a circle. Let a particle describe half a circle of radius R in time τ. Obviously, that is, average speed as the modulus of the average velocity vector is not the same as the average speed defined as the total length of the path traversed divided by time elapsed.Read more on Sarthaks.com - https://www.sarthaks.com/451378/average-speed-can-mean-the-magnitude-of-the-average-velocity-vector-another-meaning-given
