Question

how does the velocity of the cyclists compare to their speed? a. the velocity is changing because the cyclists are changing direction. b. the velocity is constant because the speed is not changing. c. the velocity is as fast as the speed but in the opposite direction. d. the velocity is faster than the speed but in the same direction.

Explanation:

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction). If cyclists change direction, their velocity changes even if speed remains constant.

Answer:

A. The velocity is changing because the cyclists are changing direction.
