In this study, we explore the kinematics of multiple populations in the globular cluster 47 Tucanae by combining data from JWST, HST, Gaia, and ground-based telescopes. We analyzed velocity dispersion and anisotropy profiles from the cluster center out to $\\sim$10$R_h$. Our findings indicate that while first population (1G) stars' motions are isotropic, second population (2G) stars' motions are significantly radially anisotropic.
