Motion in a Plane: Foundations of Two-Dimensional Kinematics

Understanding how objects move in two dimensions is fundamental to mastering classical mechanics, whether you are preparing for academic exams or exploring the physics of real-world motion. This text-based course guides you from basic physical quantities to complex two-dimensional trajectories. You will learn to break down motion into independent horizontal and vertical components, analyze vector quantities, and solve kinematics problems with confidence. What you'll learn: 1. Understand fundamental concepts of scalars, vectors, and coordinate systems in two dimensions. 2. Calculate projectile motion parameters including time of flight, maximum height, and horizontal range. 3. Analyze uniform circular motion and understand centripetal acceleration and angular velocity. 4. Apply vector addition, subtraction, and resolution techniques to physical scenarios. 5. Solve relative velocity problems in a plane, such as river-crossing and wind-resistance challenges. 6. Explore modern applications of two-dimensional kinematics in computer graphics and robotics pathfinding. The course starts with essential definitions of vector algebra before moving systematically through projectile trajectories, circular motion, and relative velocity. Each concept is reinforced with detailed written walkthroughs and practice problems to build your analytical skills. This course is designed for introductory physics students, exam candidates, and beginners looking for a solid foundation in mechanics, with no prior advanced physics experience required.
