About this course

Classical mechanics requires a strong grasp of how physical systems move and interact, especially when dealing with rotating objects and large-scale forces like gravity. This course is designed to provide a comprehensive, text-based foundation in two essential areas of physics: rigid body dynamics and universal gravitation. Upon completion, you will have mastered the fundamental principles governing rotational equilibrium, the mechanics of rigid bodies, and the laws of universal gravitation, preparing you to tackle complex problems in engineering and advanced physics. What you'll learn: * Understand the foundational concepts of torque, angular momentum, and rotational equilibrium. * Calculate the moment of inertia using parallel and perpendicular axis theorems for various rigid bodies. * Apply conservation laws to analyze complex systems involving rolling motion and coupled rotation. * Master Newton's Law of Universal Gravitation and calculate gravitational potential energy and escape velocity. * Analyze orbital mechanics, including Kepler's Laws and the dynamics of satellite motion. * Practice using vector methods to describe and solve problems in rotational kinematics and dynamics. The course begins by defining key terminology and mathematical tools for rotational motion, progressing through the calculation of moments of inertia and the application of conservation laws. The second half covers the theoretical framework of gravitation, leading into practical analysis of planetary motion and satellites. This program is ideal for beginners with no prior experience in these topics. All you need is a basic understanding of algebra and linear motion concepts. Start reading today and build your physics foundation.
