Under what conditions can a body travel a certain distance and yet its resultant displacement be zero ?

Can distance be zero, even when displacement is not zero ?

If the distance covered is zero, the displacement:-

A particle is moving on a cicular path of radius 'R' . As it moves through an angular displacement theta , its linear displacement will be :

An object is placed at a distance of 40 cm from a concave mirrorr of focal length 15 cm . If the object is displaced through a distance of 20 cm towards the mirrorr, the displacement of the image will be

If a particle is executing SHM , with an amplitude A , the distance moved and the displacement of the body during its time period is

Distance is a scalar quantity. Displacement is a vector quqntity. The magnitude of displacement is always less than or equal to distance. For a moving body displacement can be zero but distance cannot be zero. Same concept is applicable regarding velocity and speed. Acceleration is the rate of change of velocity. If acceleration is constant, then equations of kinematics are applicable for one dimensional motion under the gravity in which air resistance is considered, then the value of acceleration depends on the density of medium. Each motion is measured with respect of frame of reference. Relative velocity may be greater // smaller to the individual velocities. A particle moves from A to B. Then the ratio of distance to displacement is :-
