Exam-style question
Try this first
Which of the following correctly describes how increasing torque affects rotational power at a constant angular speed?.
- A.Rotational power increases
- B.Rotational power decreases
- C.Rotational power remains constant
- D.Rotational power becomes zero
Model answer
What a good answer should say
- Rotational power increases
Explanation
Why this works
According to the formula Power = Torque x Angular Speed, if torque increases while angular speed remains constant, the rotational power must also increase. This demonstrates the direct relationship between torque and power.
