Question

what is the distance travelled by a body and its displacement when it completes one revolution around a circular track with radius r​

Answer 1

What is the distance traveled by a body and its displacement when it completes one revolution around a circular track with radius r​?

Answer:

The distance travelled is 2πr

Answer 2

Answer:

Distance is 2πr

Displacement is Zero

Explanation:

A body completing one revolution around a circular track with radius r will cover a distance that is equivalent to the circumference of the circular track. Therefore the distance is 2πr i.e the circumference of the track with radius r.

Displacement is the distance between the object's starting point and ending point. However since the object completed a complete revolution around a circular track its starting and ending point are the same therefore the displacement is zero as the distance between the starting and ending point is zero
