Question

displacement may be zero even distance travelled is not zero? is it true ?is the reverse of this is true ?give example

Answer 1

hello....
yes it is true that displacement may be zero even distance travelled is not zero....
Example : an athlete run in a circular motion start from an end and finish on the same end in this case the diplacement is zero but distance travelled is not zero.....
the reverse of this statement is not true ....

Answer 2

Hey there !!



Displacement is the shortest distance possible between initial and final position.
It is not always necessary that when displacement is zero , distance need not be always zero.

Distance becomes zero when the object is at rest [ when it is not moving ]

Lets take an example where displacement is zero , but distance covered is not zero.:
An object moving in circular path has displacement zero .
This is because the initial and final position are the same.
But , in this case , even if displacement is zero , distance covered is not zero and is equal to the circumference of the circle

-----------------------------------------------------

If the distance traveled is zero, then it means the person or the body is at rest.[ did not move from initial position]
Hence, in such case , the displacement is zero.
