Question

Velocity vector in circular motion is always

• A. Perpendicular to the circle
• B. Tangent to the circle
• C. Opposite to the direction of object's motion
• D. None

Answer 1

Answer: (B)

Tangent to the circle

At all instances, the object is moving tangent to the circle. Since the direction of velocity vector is the same as the direction of the object's motion, the velocity vector is directed tangent to the circle as well.
