1.

the displacement of a moving object in a given interval of time is zero . would the distance traveled by the object also be zero .justify.

Answer»

Distance is a SCALAR quantity .


So only its MAGNITUDE is taken.

Distance is ZERO in below cases-----


For a static object ,the distance traveled is zero.


The distance from a point to the same point is zero.


The relative distance according to the observer traveling with same speed is ALSO zero.
______________
---------------

But distance can't be negative.

Even if taken in negative or opposite side only its magnitude is considered.

Let an object travels along the sides of a triangle ABC.

It starts from Point A and goes to B then C then A .



Now its DISPLACEMENT is the minimum distance between its final and initial position.
That is zero this time.


But its distance traveled is the perimeter of the triangle ABC.
