Question

Displacement may be 0 even when distance travelled is not zero. Is it true? Is the reverse also true? Give example

Answer 1

Answer: yes it is true as displacement is independent of the distance travelled. For eg : if a body moves in a circular path then on completing one revolution it returns to it's initial point. So in this case the body travelled some distance but the displacement is zero as it returns to it's initial position. No the reverse is not true as distance travelled is dependent on displacement. If a body has displacement then it is obvious that the body has travelled some distance as displacement means the shortest straight line distance between the final and the initial point. So if displacement is done then distance cannot be zero however the displacement can be zero if some distance is travelled as we have seen in the example of circular path.

Explanation:

Answer 2

Answer:-

First, statement is true.

Second, statement is wrong.

Explanation:-

Distance :- It is the length of actual path travelled by a body is known as distance.

Displacement :- It is the shortest distance between final and initial position.

Now, The difference between distance and displacement:-

• Distance is a scalar quantity, Displacement is a vector quantity.

• Distance never be 0 . Displacement may be 0.

• Distance can not be in negative displacement may be negative.

• Distance is always greater and equal to 0 but not less than displacement.

Now, The relation between distance and displacement,

$\boxed{\sf{\dfrac{S}{\vec{S} }\geq 1}}$

Example :-

When a body moves in a circular path makes one revolution then distance cover will be equal to its circumference but displacement will be 0.
