Laws of pendulum

• The laws of a Simple Pendulum describe the behavior of a pendulum undergoing Simple Harmonic Motion (SHM). 
• A simple pendulum is a mass (called the bob) attached to a string or rod, which is hung from a pivot point. 
• The following are the laws of a Simple Pendulum:

Law of Periodicity: 

• The time period of a simple pendulum is independent of its amplitude (the maximum angle of displacement from its equilibrium position) and is solely dependent on its length. 
• This means that the time it takes for a pendulum to complete one full cycle of its motion is constant, regardless of the angle of displacement.

Law of Isochronism: 

• The time period of a simple pendulum is the same for small angles of displacement, regardless of the amplitude. 
• This means that the time it takes for a pendulum to complete one full cycle of its motion is the same for small angles of displacement, regardless of the size of the displacement.

Law of Restoring Force: 

• The restoring force acting on a simple pendulum is proportional to its displacement from its equilibrium position and always directed towards it. 
• This means that the force that tries to restore the pendulum to its equilibrium position increases as the pendulum moves further away from it.
