Question

What is the average velocity of a body completes one circular motion of radius 'r'

1 point

2πr

Zero

πr

πr/2​

Answer 1

Answer:

I think πr

please mark me brain list

Answer 2

Answer:

For a body moving along a circular path, its displacement can at maximum be 2r (when the object has moved to the other end of diameter) and minimum can be zero, but the distance travelled by the object is along the arc of the circuit which is always greater then the displacement.

And, Averagevelocity=

Totaltime

Totaldisplacement

Averagespeed=

Totaltime

Totaldistance

∴Averagespeed>Averagevelocity
