Amplitude
Which of the following is true? (SELECT ALL THAT APPLY.)
A simple harmonic oscillator has the greatest kinetic energy at equilibrium.
A simple harmonic oscillator has the greatest potential energy at its turning points.
Every oscillation, kinetic energy and potential energy reach their greatest values twice, but never at the same time.
For any oscillation, either the period (in sec) or the frequency (in Hz) is greater than 1.
All waves require oscillation (or vibrations), but not all oscillations result in waves.
