Conquer Physics

Turn physics from memorized formulas into ideas you can explain and problems you can solve. Conquer Physics builds a complete mechanics and electromagnetism foundation in 16 chapters: Mechanics • Vectors, components, dot and cross products, dimensional analysis • Kinematics: position, velocity, acceleration, motion graphs, projectiles, relative motion, circular motion • Newton's laws: free-body diagrams, friction, inclines, tension, circular dynamics, terminal velocity • Work, energy, and power: kinetic-energy theorem, potential energy, conservation, springs, power • Momentum and center of mass: impulse, collisions, center-of-mass motion, variable mass • Rotation I: angular kinematics, torque, moment of inertia, rotational energy • Rotation II: parallel-axis theorem, angular momentum, rolling, rigid-body equilibrium • Simple harmonic motion: phase, angular frequency, energy, pendulums • Universal gravitation: field, potential energy, escape speed, Kepler's laws Electromagnetism • Electrostatics: Coulomb's law, electric field, potential, continuous charge • Gauss's law: flux, symmetry, conductors, common distributions • Capacitors: capacitance, series and parallel, dielectrics, stored energy • Circuit analysis: current, resistance, Kirchhoff's laws, RC circuits, meters • Magnetic fields: forces, charged-particle motion, fields from currents, Ampere's law • Electromagnetic induction: Faraday's law, motional emf, Lenz's law, transformers, Maxwell's equations • Inductors: self-inductance, magnetic energy, RL circuits, LC oscillations Every concept includes an intuition-first summary, definition, key points, validity conditions, original worked examples, pitfalls, and a tip. Practice mixes multiple-choice and free-response questions with full explanations, model answers, and self-assessment rubrics. Every figure is drawn natively by the app. Trilingual interface: Traditional Chinese, Simplified Chinese, English, with a Follow phone option. No account, no ads, no third-party tracking SDKs. Learning progress stays on your device, and downloaded lessons work offline.
