SUMMARY
The formula that relates the period of a pendulum in a rotating coordinate system to the angular velocity is derived from the principles of classical mechanics. The period T of a simple pendulum can be expressed as T = 2π√(L/g_eff), where g_eff = g - ω²L, with g being the gravitational acceleration (approximately 9.81 m/s²) and ω representing the angular velocity of the rotating system. This adjustment accounts for the effective gravitational force acting on the pendulum due to the rotation. Understanding this relationship is crucial for analyzing pendulum behavior in non-inertial reference frames.
