Describe the energy variation of a simple pendulum whaen it is performing the simple harmonic motion.

The velocity of the bob is maximum when it is at the equilibrium conditionhence the kinetic energy is maximum and then potential energy is minimum we can say that potential energy is zero if we take the reference level athe equilibrium position. and at the extremum position its velocity is zero that means the kinetic energy will be zero but the potential energy will be maximum.but at every inatant of the whole process the energy remains conserved that is we can say thatat every instant of a body performing simple harmonic motion

THE TOTAL ENERGY = MAXIMUM KINETIC ENERGY = MAXIMUM POTENTIAL ENERGY = TOTAL ENERGY AT ANY OTHER STATE
