Charged Physics Lab turns the Physics I and Physics II formula sheet into an interactive problem-solving workspace. Start with the language in a homework problem, a quantity you need, or a formula you recognize. Search across 200 equations or browse the Formula Map by physics section. Open a formula to see its variables, fixed units, physical meaning, and a diagram that responds to the values in the equation. The equation itself is the calculator. Tap a variable tile to enter a value. Hold a tile to isolate that variable automatically, or use a short hold and swipe to make one inverse algebra move yourself. When every required value is known, the result appears immediately. For multi-step problems, carry a solved quantity into a related formula and keep the calculation on the same working blackboard. Formula search surfaces useful next equations when a result can feed another step. Teacher-style worked examples combine the physical story, a labeled visual, symbolic rearrangement, substitution, units, and interpretation. Narration and the visual presentation move together so you can follow the reasoning instead of only seeing a final answer. Included: • 200 Physics I and Physics II equations • Plain-English, symbol, quantity, and topic search • Interactive variable tiles with fixed units • Automatic isolation and step-by-step algebra gestures • Live diagrams and variable explanations • Narrated worked examples • Multi-formula problem chains • A built-in How to Use guide • On-device progress and settings • Core learning content available without an internet connection Charged Physics Lab is a learning and calculation aid. Always use the assumptions and sign conventions appropriate to your course and problem.
