<![CDATA[Physics learning about motion concepts is often abstract, while traditional games with embedded scientific principles are increasingly overlooked. This study addresses both issues by developing a Virtual Reality (VR)–based physics simulator inspired by the traditional Tong Glinding game. Designed as an interactive virtual laboratory, the simulator allows users to adjust the incline angle (1°–6°), choose a smooth or rough surface, and observe the motion of a rolling barrel along a 20-meter track. Developed using the Research and Development (R&D) method with the ADDIE model and implemented in Unity 3D, the system integrates cultural heritage with immersive VR experimentation. Functional testing confirmed 100% conformity to design specifications. Simulation verification demonstrated high accuracy, with errors of only 1.8%–2.5% between simulation and analytical calculations on the smooth surface, while the rough surface correctly produced no motion at low angles. User experience testing with 30 participants yielded a high overall score of 87.5 out of 100, supported by strong reliability across all dimensions (Cronbach’s α = 0.85–0.92). These results show that the simulator is technically reliable, physically accurate, and well-received as a learning medium. The combination of cultural preservation and interactive VR-based experimentation represents the novelty of this work.]]>
