Mechanics Mastery
Master mechanics in the order physicists think: first describe motion (kinematics), then explain it (forces), then use energy and momentum shortcuts, then conquer rotation and gravity. Simulations and worked examples are woven into every module.
Module 1: Kinematics: describing motion
Position, velocity and acceleration — the vocabulary of motion, plus motion graphs.
Learn
- Vectors vs Scalars — The Two Kinds of Quantities in Physics
- Acceleration — Definition, Formula and Worked Examples
- Graphing Motion — Reading Position, Velocity and Acceleration Graphs
Practice
Module 2: Newton's laws and forces
The three laws, free-body diagrams, and friction — why motion changes.
Learn
- Newton's First Law of Motion — Inertia Explained
- Newton's Second Law — F = ma Explained with Examples
- Newton's Third Law — Action and Reaction, Clearly Explained
- Friction Force — Static vs Kinetic Friction Explained
