Which of the following statements is correct about angular acceleratio...
Understanding Angular Acceleration
Angular acceleration is a crucial concept in rotational dynamics, representing how quickly an object's angular velocity changes over time.
Correct Statement: Option A
- Angular acceleration is defined as the rate of change of angular velocity with respect to time. This means that if an object is rotating and its speed of rotation changes, the angular acceleration quantifies that change.
Explanation of Other Options
- Option B: Angular acceleration is not the same as tangential acceleration. Tangential acceleration refers to the linear acceleration along the circular path, while angular acceleration deals with the change in rotational speed.
- Option C: In uniform circular motion, the object moves at a constant speed. Therefore, the angular acceleration is zero because there is no change in angular velocity, making this statement incorrect.
- Option D: Angular acceleration is not independent of the radius. While it can be calculated using the formula involving tangential acceleration and radius, the radius can influence how angular acceleration manifests in terms of linear acceleration.
Conclusion
In summary, the correct understanding of angular acceleration is essential for solving problems in rotational motion, particularly in physics and engineering contexts. Option A accurately captures this concept, while the other options misrepresent key principles of rotational dynamics.

Which of the following statements is correct about angular acceleratio...
Angular acceleration is defined as the rate at which an object's angular velocity changes over time. It is given by the formula:
Angular acceleration (α) = Change in angular velocity (Δω) / Change in time (Δt)
Angular acceleration (α) = Change in angular velocity (Δω) / Change in time (Δt)
