Final answer:
The velocity vector in uniform circular motion is always tangent to the circle.
Step-by-step explanation:
In uniform circular motion, the velocity vector is tangent to the circle, and the centripetal acceleration vector points towards the center of the circle. Both vectors have specific characteristics that can help us identify them.
The velocity vector represents the direction and magnitude of the object's speed. It is always tangential to the circular path, meaning it points in the direction of motion along the circle.
Therefore, any vector that is tangent to the circle could represent the velocity vector.
