Meaning of the Terms Distance and Displacement

The position of a particle at different times are given below.

The displacement of the particle from $\mathrm{A}$ to $\mathrm{B}$ is

A boy walks around a circular track of radius $14 \mathrm{m}$, such that after $2$ minutes he is diametrically opposite to the starting point.

If a person could fly non-stop around the equator of earth and reaches back at initial point, the displacement is:

A boy running around a circular track of radius $7 \mathrm{m}$ returns back to the starting point after completing two rounds. The distance covered by the boy and the displacement is : (Take the value of $\mathrm{\pi }$ as $\frac{22}{7}$)

The shortest distance covered by a moving body from its initial position to its final position is called :

SI unit for measuring distance is :

The actual length of the path travelled by a body, irrespective of its direction of motion is called:

State the SI unit of distance and displacement.

A person starts from his house and travels a circular distance of $15 \mathrm{km}$ around the walled city before returning back. What is the distance covered by person, and the displacement of the person?

A body is moving along a circular path of radius $\mathrm{R}$. What will be the distance covered and the displacement of the body after half a revolution?

The displacement of a moving object in a given interval of time is zero. Would the distance travelled by the object also be zero? Justify your answer.

State two differences between distance and displacement.

What do you understand by the terms: (i)Distance (ii) Displacement ?

 Give an example of a body which covers a known distance, but its displacement is zero.

What is the numerical ratio of displacement to distance for a moving object?

Give the name of physical quantity that correspond to the shortest distance between the initial and final position of a moving body.
