Simple Pendulum

                         Figure: H.2

We will find the equation of motion of a simple pendulum,

Torque on the body w.r.t the centre is given by,

If  then

       

   

   

   

       

So the motion of a simple pendulum is a SHM.

  

         

Therefore, the time period of oscillation is given by,

      

    

Where  is the length of the pendulum.
