Exam-style question
Try this first
In a system where the moment of inertia increases, what happens to the angular acceleration if the applied torque remains constant?.
- A.Angular acceleration increases.
- B.Angular acceleration decreases.
- C.Angular acceleration remains the same.
- D.Angular acceleration becomes zero.
Model answer
What a good answer should say
- Angular acceleration decreases.
Explanation
Why this works
According to the relationship τ = Iα, if torque is constant and moment of inertia increases, angular acceleration must decrease since they are inversely proportional.
