Fundamentals of Automotive Physical Science and Undercar Systems

Every turn of a steering wheel, press of a brake pedal, and bump in the road relies on fundamental principles of physical science. Understanding these forces is the key to diagnosing and repairing modern vehicles effectively. This text-only course guides you through the essential physics of undercar systems, including steering, suspension, and braking. You will transition from a curious beginner to someone who understands how mechanical forces, hydraulics, and friction keep a vehicle safely on the road. What you'll learn: - Understand the physical principles of force, leverage, and friction as they apply to automotive systems. - Explore the mechanics of steering and suspension systems, including modern electronic power steering. - Analyze braking systems, hydraulics, and the fundamental physics of stopping power, including modern regenerative braking concepts. - Examine wheel alignment angles and how geometry affects vehicle handling and tire wear. - Practice identifying common undercar component failures through written diagnostic scenarios. We begin by establishing foundational definitions of physics—such as force, pressure, and friction—before exploring how these concepts operate within real-world automotive components. You will read detailed explanations of mechanical linkages, hydraulic circuits, and modern electronic assists, reinforcing your learning with written diagnostic exercises. This course is designed for aspiring automotive technicians, DIY enthusiasts, and anyone curious about how cars work, with no prior experience in automotive mechanics or advanced physics required.
