Citlin vs Newtonic

忘却曲線に基づいた最適なタイミングで、英単語を出題する英単語学習アプリ

Newtonic turns 59 physics topics into simulations you can push around. Throw a ball and watch the range change with the angle. Swing a double pendulum into chaos. Bend light around a galaxy. Fire an electron at a barrier and watch part of it tunnel through. Every topic comes three ways: • Simulate: change real quantities, in real units, and watch the system answer. Every readout is computed from the actual equations. • Learn: the formulas with every symbol explained, a short plain-language explanation, the key ideas and guided experiments to try. • Quiz: a few questions with explanations, so you know what you understood before the exam does. Earn XP as you explore, read and take quizzes, keep a daily streak and collect 19 badges along the way. Tell Newtonic your level and favorite fields, and Home suggests what to try next. 59 simulations across 11 fields: classical mechanics, gravity and orbits, fluids, oscillations, waves and sound, thermodynamics, electricity and magnetism, optics and light, relativity, quantum mechanics, and atomic and nuclear physics. Made for high school and university students, whether you're studying for an exam or meeting physics for the first time. Works offline. No account, no ads, no tracking. On iPad, the controls sit beside the simulation and every field is one tap away. Free and Pro 18 simulations are free forever, at least one in every field.
