If the magnitude of average speed and average velocity over a time interval are the same, then:

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

On an open ground,a motorist follows a track that turns to his left by an angle of $60^{\circ}$ after every $500\; m$. Starting from a given turn,specify the displacement of the motorist at the third,sixth and eighth turn. Compare the magnitude of the displacement with the total path length covered by the motorist in each case.

$A$ particle moves along the circumference of a circle of radius $r$ from point $A$ to point $B$ as shown in the figure. What are the path length and displacement?

Are motion and position relative or not?

The ratio of displacement to distance for a moving particle is
