A simple pendulum hanging freely and at rest is vertical because in that position

A simple body hanging freely and at rest is vertical because in that position.

Ideal simple pendulum can not exist practically because

A simple pendulum is released from rest at the horizontally stretched position. When the string makes an angle theta with the vertical, the angle theta which the acceleration vector of the bob makes with the string is given by–

A simple pendulum is released from rest with the string in horizontal position. The vertical component of the velocity of the bob becomes maximum, when the string makes an angle theta with the vertical. The angle theta is equal to
