Fundamentals of Motion, Work, Energy, and Power

Physics is the foundation of all engineering and science, and mastering the concepts of motion and energy is the essential first step. Many beginners struggle to connect abstract physical principles to real-world phenomena. This course provides a clear, conceptual pathway to understanding the fundamental laws governing how objects move and how energy is transformed and transferred. You will gain the ability to analyze basic mechanical systems and solve quantitative physics problems with confidence. What you'll learn: * Understand the definitions of displacement, velocity, and acceleration to accurately describe linear motion (kinematics). * Define work and power, and calculate the work done by constant forces acting on an object. * Master the concepts of kinetic and potential energy and the crucial principle of conservation of mechanical energy. * Apply the work-energy theorem to analyze systems where energy is transferred or transformed. * Practice solving fundamental physics problems involving momentum and collisions using written step-by-step methods. * Apply dimensional analysis and standard international units (SI) for accurate measurement and calculation. This course begins with foundational terminology and progresses systematically through kinematic equations, the work-energy theorem, and the conservation laws. Each section includes practical written exercises to reinforce conceptual understanding and problem-solving techniques. This course is designed for absolute beginners interested in classical mechanics or preparing for introductory science studies. No prior knowledge of physics or advanced mathematics is required. Begin your journey into the foundational laws of the physical world.
