Explanation:

1. For the first blank: Velocity is a vector quantity that includes speed and direction. If an object has constant velocity, its speed (the magnitude of velocity) must be constant.
2. For the second blank: Constant velocity also means the object moves in a single, unchanging direction (since velocity's direction component is constant).
3. For the third blank: If the object speeds up, slows down (changing speed) or turns (changing direction), then its velocity (which depends on both speed and direction) is changing.

Answer:

First blank: speed
Second blank: direction
Third blank: velocity
