Explain with an example that the magnitude of displacement may be zero but the corresponding path length is not zero.

Text Solution

Verified by Experts


For example, if the car starts from O, goes to P and then returns to O.
The final position coincides with the initial position and the displacement is zero.
However, the path length of this journey is OP + PO = 360 m + 360 m = 720 m.
Thus, the magnitude of displacement for a course of motion may be zero but the corresponding path length is not zero.

Explain path length.

Explain clearly, with examples, the distinction between : (a) magnitude of displacement (sometimes called distance) over an interval of time, and the total length of path covered by a particle over the same interval, (b) magnitude of average velocity over an interval of time, and the average speed over the same interval. (Average speed of a particle over an interval of time is defined as the total path length divided by the time interval]. Show in both (a) and (b) that the second quantity is either greater than or equal to the first. When is the equality sign true ? (For simplicity, consider onedimensional motion only).
