After studying the motion of a ball rolling on a straight line as shown in the figure.

Find its distance and displacement covered.

(i) when it rolls from P to Q and then to R (i.e., P to Q to R)

(ii) Finally comes back to P (i.e., P to P)(take, P as reference point).

(i) Distance would be PQ+QR = 12m whereas displacement is path PR= 8m as displacement is the shortest distance between two points.

(ii) In this case displacement is zero as initial and final point is same but distance would be PQ+QP= 20m.
