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
