thanks for the help. can someone explain the difference between non-harmonic, anharmonic and non-linear oscillation?

I am guessing that for the same value of \varphi, \varphi will be larger than \sin \varphi. So the SHM will have a larger restoring torque compared to the non-harmonic motion. Correct? So if the SHM has a greater restoring torque, it will oscillate faster. Does this means that at larger...

Using the small angle rule, \ddot{\varphi}=-\omega_0^2 \varphi So we can say that the acceleration,\ddot{\varphi} is directly proportional to the displacement, \varphi and are oppositely directed. Is this sufficient to conclude that this is harmonic motion? Is "anharmonic motion" and...

In SHM, the period is independent of the amplitude, right? Wikipedia says it is isochronous. For a non-harmonic motion, will the period increase as the amplitude increases? Take more time to cover a longer distance...

Since SHO is only true for very small angles, so I guess we have to displace the pendulum at a large angle.

For my physics lab report, we are supposed to conduct an experiment to show the non-harmonic oscillation of a simple pendulum. I know what is simple harmonic oscillation, damped oscillation, driven damped oscillation. But what is a non-harmonic oscillation? A google search reveals that there...
