Question
What is an ideal simple pendulum?

Answer

An ideal pendulum is a simple pendulum consists a heavy mass (called the bob) considered as a point mass suspended by a thread which is considered to be massless and inextensible or non-elastic, from a fixed point or rigid support and in which there is no friction between the support and the string.
