Abstract

By using the Tracker video analysis and modeling tool，the angular displacement date of a large-angle pendulum and a conical pendulum are analyzed. The law of pseudo-periodicity in a large-angle pendulum is obtained，and the formula of centripetal acceleration is precisely proved.

Key words： Tracker; conical pendulum; damping; nonlinear vibration
