Exam-style question
Try this first
If the angular speed of a rotating object doubles while the torque remains constant, what happens to the rotational power?.
- A.It doubles
- B.It triples
- C.It remains the same
- D.It halves
Model answer
What a good answer should say
- It doubles
Explanation
Why this works
Using the formula Power = Torque x Angular Speed, if the angular speed doubles and torque is constant, the power will also double. This illustrates how power is directly proportional to angular speed.
