This article investigates the significant impact of Group Theory within the field of physics, having a particular focus on its application in comprehending difficult physical systems and phenomena. This report centers on the application of Lie groups, rotational groups, the Poincaré and Lorentz groups in order explain complicated features of physics. The report methodically discusses the role of the SU (2) group in Lie groups, the exploration of the rotational symmetries of the SO(3) group, and the significance of Lorentz transformations in special relativity with results demonstrate how Group Theory explains the nature of angular momentum in quantum mechanics and the limitations of the Schrödinger equation under Lorentz transformations. In addition, how the Poincaré group in special relativity is utilized. However, the scope of Group Theory's applications in physics is vast and multifaceted, making it challenging to encapsulate all its facets in a single report. This expansive field continues to evolve, promising further insights and innovations in the understanding of the physical universe.
