Introductory Physics: Simple Machines and Levers

Understanding how forces work in everyday life is a foundational stepping stone in classical mechanics. Simple machines, especially levers, demonstrate how physical laws allow us to multiply force and move heavy loads efficiently. This course builds a strong foundation in physics by walking you through force, work, and mechanical advantage. What you will learn: - Understand key terminology including force, work, torque, and equilibrium. - Identify the core components of a lever, such as the fulcrum, effort arm, and resistance arm. - Apply the fundamental law of moments to solve basic mechanical balance problems. - Differentiate between first-class, second-class, and third-class levers. - Explore modern engineering applications and biomechanical examples of lever systems. The course starts with essential physical definitions before guiding you through step-by-step theoretical explanations and written practice problems. Designed for beginners and introductory physics students, this reading course requires no previous science background. Begin reading to develop a clear understanding of basic physics concepts.
