Displacement may be zero even when distance travelled is not zero ? Is not true ? Is the reverse also true ? Give examples.

Text Solution

Verified by Experts

Yes, it is true when final position of an object coincides with its initial position, displacement `= 0` but distance `!= 0`.
No, the reverse is not true.
i.e., when distance travelled is zero, body is at rest. There is no displacement.

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

Assertion: Displacement of a body may be zero when distance travelled by it is not zero. Reason: The displacement is the longest distance between initial and final position.

When a particle is undergoing motion, the diplacement of the particle has a magnitude that is equal to or smaller than the total distance travelled by the particle. In many cases the displacement of the particle may actually be zero, while the distance travelled by it is non-zero. Both these quantities, however depend on the frame of reference in which motion of the particle is being observed. Consider a particle which is projected in the earth's gravitational field, close to its surface, with a speed of 100sqrt(2) m//s , at an angle of 45^(@) with the horizontal in the eastward direction. Ignore air resistance and assume that the acceleration due to gravity is 10 m//s^(2) . There exists a frame (D) in which the distance travelled by the particle is minimum. This minimum distance is equal to :-

If the distance covered is zero, the displacement:-

If the displacement of a particle is zero, then distance covered by it

When is net force applied zero? Give an example.

Assertion : If the displacement of the body is zero, the distance covered by it may not be zero. Reason : Displacement is a vector quantity and distance is a scalar quantity.

Statement I: The displacement of a body may be zero, though its distance can be finite. Statement II: If the bodt moves such that finally it arrives at the initial point, then displacement is zero while distance is finite.
