Q1: Select all true statements. The KE of a simple harmonic oscillator is maximum at the maximum absolute displacements. The frequency of a simple harmonic oscillator is independent of its amplitude. A harmonic oscillator, the motion of which is reduced and brought to rest over time by friction, is an example of a damped harmonic oscillator. The period of an object moving in simple harmonic motion is the number of cycles that occur per second. Young’s Modulus depends on the...
