Question

A body is moving along a circular path of radius r what is the distance and displacement of the body when it completes two and a half revolution​

Answer 1

Answer:

Explanation:

Distance is the total path covered by the body and is scalar, whereas displacement is the shortest distance between initial and final positive with the direction from the starting point to the ending point.

Distance covered of a moving body is always positive and can never be zero or negative

However, the displacement can be positive, negative or zero.

So for the particular problem half a revolution would imply a distance equal to half the circumference=pi*r

And displacement would be the shortest distance along the diameter =2*r
