Question

write short notes the periodic motion of simple pendulum ​

Answer 1

Answer:

A simple pendulum consists of a mass m hanging from a string of length L and fixed at a pivot point P. When displaced to an initial angle and released, the pendulum will swing back and forth with periodic motion. ... with being the natural frequency of the motion.

Answer 2

Mass of a simple pendulum

varies slightly over the surface of the earth, the time period will vary slightly from place to place and will also vary with height above sea level. which makes angular acceleration directly proportional to θ, satisfying the definition of simple harmonic motion.
