The swing of the object is one of the most basic forms of motion in nature，and it is also one of the

basic contents in the mechanics course.Under the guidance of Newtonian mechanics and Lagrangian mechanics，the

mathematical calculation software Maple's powerful calculation and graphic functions are used to analyze and calculate the problems in the large-angle single pendulum，double pendulum and the Foucault pendulum motion under resistance.The simulating animations made by Maple are accurate and vivid，and reflected the physical laws of the pendulum movement.At the same time，it realizes the purpose of visual teaching.
