Statement $-1:$ For small amplitude, the motion of a simple pendulum is a S.H.M. with periodic time $\mathrm{T}=2 \pi \sqrt{(\ell / \mathrm{g}) . \text { For }}$ large amplitudes, periodic time is greater than $2 \pi \sqrt{(\ell / g)}$. Statement $-2:$ For large amplitude, the speed of the bob is more when it passes through the mid-point (equilibrium point).
