Q 3.13  Explain clearly, with examples, the distinction between :

(a) the 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

S Sayak

The magnitude of displacement is defined as the shortest distance between the initial and final position of a particle whereas the total length of path covered by a particle is the actual distance it has travelled. e.g a ball thrown upwards which goes to a height h and comes down to its starting position has its magnitude of displacement to be zero but the total length of the path covered by the ball is 2h. In the case of 1-D motion, the two will be equal if the particle moves only in one direction.
