What does a downward slope on an angular motion graph indicate?.
- A.Constant angular velocity
- B.Decreasing angular velocity
- C.Increasing angular velocity
- D.Zero angular acceleration
Model answer
What a good answer should say
- Decreasing angular velocity
Explanation
Why this works
A downward slope on an angular motion graph shows that the angular velocity is decreasing over time. This indicates that the object is slowing down in its rotation.
The implication is that there is a negative angular acceleration acting on the object. Therefore, the conclusion is that a downward slope reflects a decrease in angular velocity.
