In an angular motion graph, what does a horizontal line represent?.
- A.Constant angular velocity
- B.Zero angular acceleration
- C.Increasing angular speed
- D.Decreasing angular speed
Model answer
What a good answer should say
- Zero angular acceleration
Explanation
Why this works
A horizontal line on an angular motion graph indicates that there is no change in angular velocity over time, which means the angular acceleration is zero. This implies that the object is rotating at a constant speed.
Thus, the conclusion is that a horizontal line signifies zero angular acceleration.
