Question

An object is moving in a circle of radius r. Calculate the distance and displacement when it completes half of the circle

Answer 1

Explanation:

hope you understand the solution

Answer 2

Answer:

The distance will be the circumference of the circle so distance=pi∗r2

The displacement of any object is the distance of the object from where it started and where it is.

So when the particle completes a circle it comes back to where it was hence the displacement=0
