WavesSimulator vs Projectile Lab by ChatStick

You can conduct experiments related to waves on the app. In addition to the waves not attenuating unlike the real model, it also has useful functions such as slow playback, pause, and rewinding time. Main features - Pulse wave generation - Freehand wave generation - Generation of sine waves - Free end reflection - Fixed end reflection - Change the length of the string - Change playback speed - History display for up to 5 seconds - Glossary - 60 FPS or 120 FPS (ProMotion compatible devices only)

Projectile Lab is an interactive physics learning app that helps students understand projectile motion by doing, not memorizing. Build intuition with a real-time simulator, then deepen understanding with formula breakdowns, graph analysis, guided practice, and challenge levels. WHAT YOU CAN DO - Run live projectile simulations with adjustable angle, velocity, and launch height - Explore gravity environments including Earth and Moon (plus more with Premium) - View trajectory stats instantly: max height, range, flight time, and speed components - Learn the math with step-by-step formula sections and substituted values - Analyze motion with time-based graphs (height, distance, velocity, speed) - Practice with curated physics questions across multiple difficulty levels - Play challenge missions: hit targets, clear obstacles, land in zones, and maximize range - Save experiments to revisit and compare your best runs - Track progress through stars, streaks, and achievements DESIGNED FOR LEARNING Projectile Lab is built for students, self-learners, and educators who want a clean, focused environment for understanding motion. The app combines visual intuition and equation-level reasoning in one workflow.
