Explanation:

Speed is a scalar quantity (only magnitude), while velocity is a vector quantity (magnitude and direction). When an object moves in a circular path, its speed (magnitude of the rate of motion) can be constant. But since direction is constantly changing (as it moves along the circular path), velocity (which depends on direction) changes.

Answer:

First blank: speed; Second blank: acceleration (or change in velocity)
