If the displacement of a body is zero is it necessary that the distance covered by it is also zero
Answers
Answer:
No
Explanation:
No, its not necessary that when displacement is equal to zero then distance will also be zero.
To know why, we have to get the correct idea about these-- Distance and Displacement concept.
In a short way,
Distance is the total length covered between final and initial position. Whereas displacement is same as distance but with direction. As distance is scalar but displacement is vector quantity.
We can solve the given question by many examples, one of them is--
Let say there is an object which is in circular motion. When the object completes one full circle and comes back to its initial position then according to the definition of distance and displacement, Displacement is zero BUT distance is not zero.
Here distance is equal to the circumference of the circle which is 2πr.
No, it is not necessary if the displacement of a body is zero, the distance covered by it is always zero.
Distance is scalar quantity but displacement is a vector quantity.
For illustration. If a person is walking on a circular track of radius (r ) and completes one revolution. Then its displacement is zero but the distance coverd=2πr.
