Found is an archival research and discovery tool for exploring millions of public-domain films, photographs, audio recordings, books, and historical documents from the Internet Archive and Wikimedia Commons. Browse, read, watch, and listen โ€” completely free. Found surfaces the license and attribution for every item, so you always know exactly how a piece of media can be used. DISCOVER THE ARCHIVE Explore one of the largest collections of human culture ever assembled. Search by year, media type, creator, subject, and license type. Found's on-device recommendation engine learns your interests privately โ€” no accounts, no tracking, no data leaves your device. ORGANIZE YOUR RESEARCH Save items to personal collections. Follow archive creators and channels. Build a research library around any topic โ€” history, film, music, literature, science, or culture. KNOW YOUR RIGHTS Every item in Found displays its source, license type, and rights information. Found Pro users get a one-tap attribution generator that produces properly formatted credit text for any item โ€” ready to copy into a paper, article, video description, or creative project.

About

Charged Physics Lab

Read full description

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: โ€ข 200 Physics I and Physics II equations โ€ข Plain-English, symbol, quantity, and topic search โ€ข Interactive variable tiles with fixed units โ€ข Automatic isolation and step-by-step algebra gestures โ€ข Live diagrams and variable explanations โ€ข Narrated worked examples โ€ข Multi-formula problem chains โ€ข A built-in How to Use guide โ€ข On-device progress and settings โ€ข 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.
