When is a Pendulum in Simple Harmonic Motion?

The video tutorial explains simple harmonic motion (SHM), focusing on the conditions required for an object to exhibit SHM, such as the presence of a restoring force proportional to displacement. It compares the mass spring system and pendulum, highlighting differences in displacement types. The tutorial discusses velocities and accelerations at various positions in SHM and identifies the restoring force for a pendulum as the tangential component of gravity. The small-angle approximation is introduced, explaining its relevance to pendulum SHM.

What is required for an object to be in simple harmonic motion?

What distinguishes the displacement in a mass spring system from that in a pendulum?

At which position is the velocity of an object in simple harmonic motion at its maximum?

What is the restoring force for a pendulum in simple harmonic motion?

Why is a pendulum considered to be in simple harmonic motion only for small angles?
