One of the following statements is incorrect, (a) The car traveled around the track at a constant velocity. (b) The car traveled around the track at a constant speed. Which statement is incorrect and why?

(b) The car traveled around a track with constant velocity is incorrect

Explanation:

We know that velocity is vector quantity and speed is scalar quantity

As in the car traveled around the track its direction will change at every instant so velocity can not be constant as its depends on both magnitude as well as direction.

Speed is a scalar quantity which only depends on the magnitude and the speed can be constant around the track

So option (a) is incorrect statement
