Dimensional analysis
Use dimensional analysis to determine how the period T of a pendulum (the elapsed time for a complete cycle of motion) depends on some , or all , of these properties : the length L of the pendulum ,the mass m of the pendulum bob , and the gravitational field strength g (in m/s^2) Assume that the amplitude of the swing (the maximum angle that string makes with the vertical) has no effect on the period .( see the figure at “click here” )
