About
Buoyancy Practice is an offline study tool focused on middle school physics topics about buoyancy. It is designed for after-class review, exam preparation, and parent-guided practice. The app covers Archimedes' principle, floating and sinking conditions, liquid pressure, displaced volume, and other common test points. Key features: 1. Formula lookup: Review Archimedes' principle, floating conditions, density relationships, liquid pressure formulas, and unit notes. 2. Step-by-step calculator: Enter density, volume, weight, displaced liquid volume, and related values to generate a clear calculation process. 3. Focused practice bank: Practice by topic, including floating, suspension, sinking, weighing method, and liquid pressure mixed problems, with difficulty filters. 4. Mistake review: Keep local records of wrong answers, error reasons, retry results, and mastery status. 5. Custom questions: Manually add teacher-assigned problems, solution steps, and notes. The app requires no login, registration, or network connection. It does not collect personal information. All practice records and mistake data are stored only on the user's device.
