what is S.H.M IE SIMPLE HARMONIC MOTION AND IT APLLICATION (SIMPLE PENDULUM)

The motion is periodic, as it repeats itself at standard intervals in a specific manner - described as being sinusoidal, with constant amplitude. It is characterized by its amplitude (which is always positive), its period which is the time for a single oscillation, its frequency which is the number of cycles per unit time, and its phase, which determines the starting point on the sine wave

the formula for time period of a simple pendulum is :
