Question

a body is moving along a circular pathh of radius r find the distance and displacement in half revolution​

Answer 1

Distance is the total length covered,

when the bidy covers have revolution then

distance = πr

displacement is the shortest distance between the initial and the final point

that is here diameter isnthe shortes distance

so,

displacement = 2r

Answer 2

I hope this helps

Distance is the actual path travelled by the object

Displacement is the shortest distance between the initial and final position

I hope this helps
