物理实验APP是一款专为物理学习者打造的实验模拟应用，聚焦物理学史上的里程碑实验，通过模拟呈现与解析，让用户轻松探索物理奥秘。 核心功能 收录了从牛顿经典力学到现代量子物理的数个里程碑实验，如法拉第电磁感应、密立根油滴实验、卢瑟福散射实验等。用户不仅可以观看模拟视频，还能通过拖拽参数手动操控实验变量，实时观察实验现象的细微变化。 每个实验均配备 “两位一体” 解析包： 原理看板：用动态推导式讲解核心公式，直观呈现公式与实验现象的关联逻辑 实验意义：剖析该实验如何改变了人类文明进程 该应用以简洁易用的设计、专业丰富的内容，为用户搭建了高效的物理学习平台，无论是学生辅助课程学习，还是物理爱好者拓展认知，都能从中获得优质体验。 【VIP会员自动续订说明】 订阅周期：1周（VIP会员连续包周）。 付款：用户确认购买并付款后记入iTunes账户。 取消续订：如需取消续订，请在当前订阅周期到期前24小时之前手动在iTunes/Apple ID设置管理中关闭自动续订功能。 续订：苹果iTunes账户会在到期前24小时内扣费，扣费成功后续订周期顺延一个订阅周期。 隐私政策：http://xnkj.xiaonietx.top/account/avadakedavraa/all/D6Oo0r9SDyzNc09Q5LgBLJ6LVecTY4prby.html 用户服务协议：http://xnkj.xiaonietx.top/account/avadakedavraa/all/hEneyG2V1eN.html

Twenty-six rooms. Not a workbook — a bench in each one. You set the parts out yourself, turn the knobs, and measure with the instruments. • Hang as many weights as you like anywhere along a balance beam, and even it up • Drag molecules onto the bench and see what they form • Set a magma's silica and the depth where it freezes, erupt it, then look at the rock through a hand lens and measure the grains • Stretch two strings, detune one, and listen to the beats • Drop three seismometers on a map; three circles meet at one point, and that point is the epicenter Every number is measured off the picture. Nothing here works a value out of a formula and then "checks" it against the same formula. The grains under the lens are really drawn, and their size is really measured. Turn a knob and the picture changes; when the picture changes, the numbers change with it. Every room has three steps: 1. Move it — turn one knob and watch what changes 2. Count it — line the measurement up against the formula and look at the gap 3. Check it — one question, and the reason either way Every room also has a question box. Clear it and the room moves up a tier: none → bronze → silver → gold. There are 78 questions in all. But the questions are not the main act. Playing with the bench is; a question is the detour you take when you think “wait — could I actually build that?” The topics are middle school and high school science: forces and motion, springs and buoyancy, pendulums, circuits, electromagnets, ray optics, lenses, sound, changes of state, solubility, titration, electrolysis, chemical reactions, preparing and collecting gases, the microscope, cell division, photosynthesis, flower structure, heredity, strata, rocks and volcanoes, earthquakes, and the sky. Three neighbors of science come along too: probability, logic gates and regular expressions. ADS AND THE ONE-TIME PURCHASE The app is free and shows ads: a banner along the bottom of the screen, and a full-screen ad when you open the app. All 26 rooms and all 78 questions are open from the first launch. There is exactly one in-app purchase and all it does is turn the ads off — it unlocks nothing and adds nothing. It is a single one-time purchase with no subscription (¥5,000 in Japan; the price for your country is shown in the app). Not based on, or affiliated with, any particular textbook.
