Exam-style question
Try this first
A wheel is in rotational equilibrium. If the total torque acting on it is zero, what can be concluded about the angular acceleration of the wheel?.
Model answer
What a good answer should say
- The angular acceleration of the wheel is zero.
Explanation
Why this works
This answer is strong because it directly relates to the principle of rotational equilibrium, which states that if the net torque is zero, the object does not accelerate. This question tests the understanding of the relationship between torque and angular acceleration.
