About
Lever Pulley Coach is an offline practice app designed for middle school physics mechanics. It is useful after class, before exams, or during parent-guided study. The app focuses on common problem areas: lever balance, pulley force analysis, rope segment counting, and mechanical efficiency calculations. Topic-based drills, step-by-step drafts, and mistake review help learners strengthen both formula understanding and calculation habits. Main features: 1. Lever balance practice: covers moment arms, effort, resistance, fulcrum position, and related question types with step entry and answer checking. 2. Pulley system calculations: practice rope segment judgment, force saving, pull direction, object weight, and rope-end force conversion. 3. Mechanical efficiency topics: includes useful work, total work, extra work, and reverse efficiency calculation. 4. Drafts and formula hints: record key values, unit conversions, force relationships, and calculation steps. 5. Mistake review: automatically save incorrect questions, filter by topic, and track accuracy and mastery. 6. Local question bank: built-in offline templates support custom questions and saved review records. All data is stored only on the device. No login, network connection, or personal data collection is required.
