A body performing circular motion with a constant speed has a constant:
Correct answer: B. Angular velocity
- A. momentum
- B. Angular velocity
- C. Acceleration
- D. Radius vector
Explanation
When an object moves along a circle at constant speed, v, its angular velocity about the circle's center is also constant, and the object is said to move with uniform circular motion. Although the object's speed is constant, its direction of motion keeps changing, being always tangent to the circular path.
