Good explanation but how to find moment of inertia (I) for pendulum and why to compare with SHM equation? Thanks.

[@CHINMAY_ACADEMY]

Actually M.I. formula we have directly taken from Physics...and as the oscillations of simple pendulum is S.H.M. (The motion which repeats after regular interval of time) & hence it is compared with the SHM equation. Thanks !!!
