Lever Pulley Physics Coach2026

Offline middle school physics practice for lever balance, pulley systems, mechanical efficiency, drafts, and mistake review.

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.
