It is impossible for two particles, each executing simple harmonic motion, to remain in phase with each other if they have different:
A)masses
B)periods
C)amplitudes
D)spring constants
E)kinetic energies

Question

Quizplus · Accepted Answer

The period of an oscillator depends only on the mass and spring constant, and not on the amplitude or kinetic energy. Therefore, if two particles have different periods, they cannot remain in phase with each other over time.
