With this simulation, you can experiment the refraction of light between air and a transparent semi-disk. You can choose the material of the disk from a list of materials. Also, you can determine the index of refraction of the semi-disk when you apply Snell’s law to measurements you take in the simulation.
If this future becomes reality, there will be a massive wave of job displacement as AI takes over across various industries and job markets. But a wide horizon of opportunities will rise. Instead of a position of making decisions in a company, there will be a position of training the AI to make that decision and to maintain its logic.
As a bizarre example, companies might not need IT (Information Technology) officers anymore! Instead, they might employ AIT (Artificial Intelligence Technology) officers, whose main responsibility is training and maintaining the company’s AI model to solve the company’s technical issues!
Using this simulation, you can experience the phenomenon of charging a metallic ball by induction in the first stage and charging the ball by contact in the second stage after the charged rod touches the ball. The displayed charges are for an illustrational purpose, and they are not seen in reality. You can disable the display of charges on the rod and on the ball.
In this simulation, you can try two situations, one in which the rod is positively charged and another in which the rod is negatively charged, and you will see that the two situations result in the same observation.
If you or your student or child are having difficulties in learning long division, then you will find this simulation comprehensive and instructional, that guides the learner through the process step by step. This application is for long division with float quotient. Another application on long division with remainder is also available in the simulations section.
القصور الذاتي هو خاصية المادة التي تقاوم التغييرات في السرعة المتجهة. عندما تكبح السيارة، يميل جسمك للأمام؛ وعندما تتسارع، تميل للخلف – كلاهما يوضح القصور الذاتي عملياً. كلما زادت كتلة جسمك، كان التأثير أكثر وضوحاً. يشمل القصور الذاتي مقاومة التغييرات في كل من مقدار السرعة واتجاه الحركة، مما يجعله مفهوماً أساسياً لفهم سلوك الأجسام.
This simulation models Newton’s tube experiment, showing how air resistance affects falling objects. By removing air from the tube and flipping it, users can observe how a feather and a pebble fall differently in air but identically in a vacuum—demonstrating that gravity accelerates all objects equally when air resistance is removed.
توضح هذه التجربة أنه عند انعدام مقاومة الهواء، يصل جسمان يسقطان بحرية من نفس الارتفاع إلى الأرض في نفس اللحظة. يكتسب كلا الجسمين نفس السرعة أثناء السقوط، مما يثبت أنهما يختبران نفس التسارع – تسارع السقوط الحر. تشرح التجربة سبب رؤيتنا للأجسام الثقيلة تسقط أسرع من الأجسام الخفيفة بسبب تأثيرات مقاومة الهواء.
