Circular Motion
Learning Time: 4-12 hours
Content: Circular motion is the study of the motion of an object in a circular orbit with constant or variable speed. This study covers angular velocity, centripetal force, rotational acceleration, rotational kinetic energy, and their practical applications. The TYT exam focuses on basic circular motion, while the AYT exam focuses on complex systems and energy analysis. The current 2025 curriculum also covers space technologies and autonomous vehicle dynamics. Learning this topic forms the basis for the analysis of rotational systems.
