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.
