Question

If the displacement is 0 is it necessary that the distance covered is also 0?

Answer 1

no it is not always until a body is in rest .
for example: car moving on a circular track

Answer 2

hello@

here is u r answer ##

___________________________________

NO IT IS NOT NECESSARY THAT THE DISTANCE COVERED IS ZERO, BECAUSE AS WE KNOW THAT DISPLACEMENT IS A VECTOR QUANTITY SO IT HAS MAGNITUDE AS WELL AS DIRECTION ALSO BUT DISTANCE IS A SCALER QUANTITY WHICH MEANS IT HAVE ONLY MAGNITUDE.
WE DENOTE DISPLACEMENT = D2-D1
SUPPOSE A BOY STARTS FROM A POINT P AND AFTER MOVING HE RETURNS TO THE INITIAL POINT P THEN D1 IS P AND DE IS ALSO P SO IF WE FIND THE DISPLACEMENT WE GOT D2-D1= 0
BUT IF WE FIND DISTANCE THEN WE GET DISTANCE = P+P=2P
