Explain how an object could have zero average velocity but non-zero average speed?


#2

Average speed v = Net displacement / Total time taken
and Average speed
${ s }_{ av }$ = Total distance travelled / Total time taken
If an object moves along a straight line starting from origin and then returns back to origin.
Average velocity = 0
and Average speed = 2s/ t
