Answer 1

${\huge{\mathfrak{\underbrace{\overbrace{\blue{Simple \:pendulum}}}}}}$

☆ A simple pendulum consist of a small metallic ball of heavy mass known as bob suspended from a rigid stand by a weightless and inextensible string. The distance between the point of suspension and the centre of gravity of the bulb is known as the lenght of the pendulum(L).

Answer 2

Answer:

A pendulum is a body suspended from a fixed support so that it swings freely back and forth under the influence of gravity. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.
