Fundamentals of Classical Dynamics: Forces and Newton's Laws

Dynamics is the study of motion and its causes, forming the essential foundation for all higher-level physics and engineering. Without a solid grasp of forces and motion, complex mechanical systems remain a mystery. By the end of this course, you will have the conceptual clarity and technical skills necessary to confidently approach and solve standard problems involving classical mechanical forces. What you'll learn: * Understand the definitions of fundamental dynamic concepts, including displacement, velocity, acceleration, and mass. * Master Newton's Three Laws of Motion and their specific application in real-world scenarios involving inertia and momentum. * Learn how to construct and interpret free-body diagrams (FBDs) to visualize and decompose all forces acting on a system. * Apply vector analysis and trigonometry to resolve forces into their component parts on inclined planes and complex multi-object systems. * Practice solving typical introductory physics problems involving friction, tension, weight, and normal forces. The course begins with clear definitions of motion and force before systematically analyzing each of Newton's laws. The final sections focus heavily on developing a rigorous, step-by-step methodology for effective written problem-solving. This course is designed specifically for absolute beginners or those needing a thorough review of classical dynamics fundamentals. No prior physics knowledge is required.
