Question

Which one of the following is not a vector quantity?
(a)-Acceleration
(b)-Instantaneous velocity
(c-)Average Speed
(d)-Average Velocity

Answer 1

Among the given options, only average speed is not a vector quantity as speed does not have a given direction so it cannot be considered as a vector quantity.so the answer is c)

Answer 2

Average speed is not a vector quantity.

Hence the correct answer is (c-) Average Speed.

Average speed can be determined by dividing the total distance traveled by one object by the elapsed time required to cover the distance.

It is a scalar quantity by nature as it can be defined by magnitude only.
