Applied Dynamics: Newton's Laws, Friction, and Circular Motion

Dynamics is the branch of physics that explains why objects move the way they do, providing the framework necessary for all subsequent studies in mechanics and engineering. This course provides a robust, text-based foundation in fundamental force analysis and motion prediction. By the end of this course, you will be able to systematically analyze physical systems using free-body diagrams, apply Newton's Laws of Motion (NLM) accurately, and confidently solve complex problems involving friction and circular movement. What you'll learn: * Understand the three Newton's Laws of Motion and the concept of inertial versus non-inertial reference frames. * Practice constructing accurate free-body diagrams to resolve forces into component vectors using trigonometry. * Analyze static and kinetic friction, calculating coefficients and applying them to inclined and horizontal surfaces. * Derive the formulas for centripetal acceleration and centripetal force in uniform and non-uniform circular motion. * Apply principles of dynamics to complex systems, including connected masses, pulleys, and vertical circles. * Configure and solve dynamic equilibrium problems where objects are either at rest or moving at a constant velocity. The course begins by establishing key definitions and the vector nature of force, progressing through the three laws of motion. We then dedicate sections to modeling frictional forces and applying NLM to objects moving in both horizontal and vertical circles, emphasizing clear algebraic manipulation and problem-solving methodologies. This course is designed for absolute beginners in physics and students seeking a rigorous refresher on classical mechanics fundamentals.
