2.4 Simple Pendulum

2.4 Simple Pendulum

Definition:

A simple pendulum consists of a mass (called the bob) attached to a string or rod of fixed length, which swings freely under the influence of gravity. For small angular displacements (less than approximately 15 degrees), the motion of a simple pendulum can be approximated as SHM.

Period of a Simple Pendulum:

The period T of a simple pendulum is given by:

T = 2π√(L/g)

Example Problem:

A simple pendulum has a length of 1.5 m. Calculate its period of oscillation.

Solution:

Using the formula for the period:

T ≈ 2.48 s
