๐ Kinematics: Motion in One Dimension
Master the core concepts of one-dimensional motion, including displacement, velocity, acceleration, and kinematic equations. **What you'll learn:** - Distinguish between displacement and distance in motion problems - Apply kinematic equations to solve complex motion scenarios - Analyze motion graphs and extract velocity and acceleration information - Solve problems involving constant acceleration in straight-line motion - Use vector conventions to handle direction in one-dimensional systems
