Introductory Physics: Forces and Interaction of Bodies

Physics explains the fundamental principles behind how physical objects move, push, pull, and affect one another. This text-based course breaks down the core concepts of mechanical interactions into easy-to-understand explanations and practical text exercises. You will build a strong scientific foundation by learning how forces operate in everyday scenarios without needing complex mathematics. What you will learn: Understand core concepts such as mass, inertia, volume, and density. Analyze gravitational, elastic, and frictional forces acting on physical bodies. Learn how to identify force balance, direction, and net force in static situations. Apply basic formulas to calculate pressure and work in fundamental physics scenarios. Practice unit conversions using standard scientific units. The course begins with clear definitions of key terminology before progressing into structured written problem-solving and fundamental laws of motion. Designed specifically for beginners and introductory students, no prior physics background is required. Start reading today to build a confident understanding of how the physical world works.
