							A pendulum consists of heavy metallic bob, suspended from a rigid support by means of a long, weightless, flexible and in extensible string having mass (m) and time period (T). The time period (T) of a simple pendulum is defined as,
T = 2π √L/g
Here, L is the length of the pendulum and g is the acceleration due to gravity.
So the period of oscillation is independent of mass but depends on length. Thus length and time period is the fundamental property of a pendulum. Therefore, length and time be based on properties of a pendulum but the mass does not.
