A pendulum is not perfect simple harmonic motion. derive theequation for the period of a pendulum from the equation for theperiod of a simple harmonic spring oscillator and Hooke's Law. Makesure to show and explain the assumption that allows us to assume itis simple harmonic motion. is there a time when it may not followthe equation you stated?What are the variable that are NOT related to the period of apendulum?
