Question

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 particular materal.

Q2:Select all true statements.

		In SHM, the greatest magnitude of the restoring force occurs at the equilibrium position.
		At resonance, the frequency of the driving force matches the natural frequency of SHO.
		All SHO have a restoring force with a magnitude proportional to displacement and opposite in sign to the displacement.
		The acceleration of the SHO has the greatest magnitude at the greatest absolute displacements.
		If a cycle of SHM takes 2 s to complete, then the frequency is 0.5 Hz.
