SAT Subject Physics Practice Question 406: Answer and Explanation
12. A bicycle wheel spins on its axis at a constant rate but has not yet made a complete rotation. Which of the following statements is correct?
A. The angular displacement is zero.
B. The linear displacement is zero.
C. The angular acceleration is zero.
D. The angular velocity is zero.
E. None of these is zero.
Correct Answer: C
The correct answer is (C). The wheel is moving at a constant rate (angular velocity). There is no angular acceleration because Δω is zero.
