Explanation:

When an object moves in a circular path, speed (a scalar quantity) can be constant. But velocity (a vector quantity, which has both magnitude and direction) changes because the direction of motion is constantly changing. Acceleration is the rate of change of velocity. So, even with constant speed, there is acceleration due to the change in velocity (because of direction - change).

Answer:

First blank: speed; Second blank: acceleration
