For angular acceleration, clockwise rotation means the torque is:
Correct answer: A. Positive
- A. Positive
- B. Negative
- C. Zero
- D. Infinite
Explanation
a) Positive:Option (a) is correct. In the context of angular acceleration, clockwise rotation means the rotation is in the positive direction. This means that the angular acceleration is positive, and the torque applied to the object causing the rotation is also positive.

About Angular Displacement
Angular displacement measures the change in a body’s angular position and is expressed in radians or degrees, with anticlockwise and clockwise directions assigned signs. It connects to arc length, angular velocity and angular acceleration, and must be distinguished from ordinary linear displacement in rotational motion.
