Trajectory prediction seeks to forecast the future motion of intelligent agents by analyzing their past trajectories. While deep learning methods have been demonstrated to capture complex features, they frequently neglect physical constraints, thereby constraining interpretability. To address this, a trajectory prediction model is proposed that integrates analytical mechanics with graph neural networks (GNNs). The model combines GNNs, convolutional neural networks, and graph attention to extract spatiotemporal dynamics, infers interaction forces from Euclidean distance and relative motion, and incorporates Lagrange mechanics to enforce physical laws. Experiments on the Spring-balls dataset demonstrate the superior performance of the proposed model in comparison to traditional models, exhibiting a 14.29% accuracy gain in 10-frame short-term prediction for the 5-ball case and improvements of 6.25% and 4.81% in 50-frame long-term scenarios. In the domain of human motion prediction, our model demonstrates a reduction in mean position error (MPJPE) when compared to prevailing approaches for a wide range of actions. This finding signifies enhanced long-term accuracy and validates the efficacy of the model.
