Describe the relationship between the direction of the velocity vector and the direction of the acceleration for a body moving in a circle at constant speed.
The velocity vector and acceleration are in the same direction.
The velocity vector is tangent to the circle, while the acceleration is directed towards the center of the circle.
The velocity vector and acceleration are perpendicular to each other.
The velocity vector is directed towards the center of the circle, while the acceleration is tangent to the circle.

If an object is in uniform circular motion and is accelerating towards the center of the circle, yet the object never gets any closer to the center of the circle, suggest a reason as to how this can be.
The object is not actually moving.
The object is moving in a straight line, not a circle.
The object's velocity is perpendicular to the acceleration, allowing it to move in a circle without getting closer to the center.
The object is slowing down, preventing it from moving closer to the center.
