Exam-style question
Try this first
If an angular motion graph shows a curve that becomes steeper, what does this imply?.
- A.Constant angular acceleration
- B.Increasing angular acceleration
- C.Decreasing angular acceleration
- D.Constant angular velocity
Model answer
What a good answer should say
- Increasing angular acceleration
Explanation
Why this works
A curve that becomes steeper on an angular motion graph indicates that the rate of change of angular velocity is increasing, which means the angular acceleration is also increasing. This implies that the object is accelerating more rapidly as it rotates.
Thus, the conclusion is that a steeper curve signifies increasing angular acceleration.
