Question

Under what conditions can we consider the oscillations of a simple pendulum to be linear simple harmonic?​

Answer 1

Answer:

The motion of Simple Pendulum as Simple Harmonic Motion

Now, if we displace the pendulum by a very small angle Θ, then it performs the simple harmonic motion. Consider a simple pendulum having mass 'm', length L and displaced by a small angle Θ with the vertical. Thus, it oscillates about its mean position.

Answer 2

Answer:

the oscillations of À simple pendulum are approximately linear simple harmonic only of (1) the amplitude if oscillation us very small compared to its length
