Features
- 1. Question card archive: Create local question cards by question types such as inclined planes, pulleys, connected bodies, springs, friction, and equilibrium
- Record question summary, conditions, known quantities, and conclusions
- 2. Force diagram drawing: Add objects, coordinate axes, and force arrows on local canvas
- Label force names, directions, magnitudes, angles, and points of application
- 3. Decomposition and equation steps: Record orthogonal decomposition, equilibrium equations, and Newton's second law steps
- Support segmenting key formulas and intermediate values
- 4. Error review: Categorize mistakes by labels such as missing forces, direction errors, friction judgment, coordinate axis selection, unit conversion, and equation omission
- 5. Template practice: Built-in common mechanics scenarios templates
- Quickly create similar questions for targeted practice
- 6. Local backup: Question cards, diagrams, review tags, and practice records can be locally saved and exported
