Introductory Physics: Motion in a Straight Line and Plane

Understanding how things move is the foundation of all physical sciences, engineering, and technology. This course breaks down the core principles of kinematics—motion in one and two dimensions—into clear, digestible written lessons. You will transition from intuitive ideas about speed and direction to a precise mathematical understanding of displacement, velocity, acceleration, and vector analysis. In this course, you will: 1. Understand fundamental terms like distance, displacement, speed, velocity, and acceleration. 2. Analyze motion in a straight line using kinematic equations and graphical representations. 3. Master vector addition, subtraction, and resolution to transition from 1D to 2D motion. 4. Solve complex projectile motion and relative velocity problems in a plane. 5. Apply coordinate systems to describe real-world physical scenarios accurately. The course starts with basic definitions and 1D motion before introducing vectors to tackle motion in a plane. Each module features step-by-step written derivations and practice problems to build your quantitative confidence. Designed for beginners, high school physics students, or anyone looking to build a rock-solid foundation in classical mechanics, this course requires no prior advanced physics background.
