Abstract	Compared with a single gravity pendulum, the spherical pendulum behaves more complicatedly in experiments, which makes it difficult to measure. In this paper, we present a method to visualize the trajectories of a spherical pendulum by employing a gravity ball with a lit LED and a digital camera. This new measurement is inexpensive and easy to use. We analyse the experimental results with the help of analytical mechanics, and give the numerical simulation for better understanding. The experiment is carried out in our physics undergraduate laboratory. Through the experiment, we can improve students' existing knowledge and evoke their creativity. (Contains 5 figures.)
