NEET 2023, Physics Q28: Kinematics and Dynamics of Rotational Motion
NEET2023Physics
Q.
The angular acceleration of a body, moving along the circumference of a circle, is:
- A
along the radius towards the centre
- B
along the tangent to its position
- C
along the axis of rotation
- D
along the radius, away from centre
Solution
Angular velocity is directed along the axis of rotation. Its time derivative is therefore also along the rotation axis.
