本题目来源于试卷: Wave Behavior C.1 Simple Harmonic Motion，类别为 IB物理学
[单选题]
Below are the graphs of the kinetic and potential energies against displacement $s$ for an object exhibiting simple harmonic motion.
Which of the positions marked on the axis represents the location of maximum speed?
A.
B.
C.
D.
参考答案: C
本题详细解析:
Explanation:
The object is going fastest through the equilibrium position. At this location, all of the energy of the system is kinetic energy. There is zero elastic potential energy at this point as there is no displacement in the spring.
