Nsaw Pendulum on Stand  (Multicolor)

NSAW Simple Pendulum on stand.A Pendulum bob weight is fixed on one end of a string and the other end of the string is suspended on a stand to form a pendulum. The system is an closed one (energy neither enters nor leaves). The total energy of each system remains constant, but it is continually changing forms. It is shared between potential energy (gravitational) and kinetic energy of motion.To study the variation of T with L for a compound pendulum (bar pendulum) and then to determine: (i) the value of the acceleration due to gravity (g) in the laboratory ,metalic bob with hook.
