Explain clearly, with ezamples, the difference between :
(a) magnitude of displacemnt (sometimes called distance ) overand
interval of time, and the total length of the path coverd by a particle over the same interval.
(b) magnitude of average velocity over an intercal of time , and the average speed
over the same interval. [ Average speed of a particle over an interval of time is defined as the toal path length
divided by the time intrval]. Show in both (a) and (b) that the second quantity is either greater than or equal to first.
When is the equality sing true ? [ For simplocity, consider one- dimensional motion only]
