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.
توقفت عن التفكير كمبرمج في تلك المرحلة وعدت إلى التفكير كفيزيائي. لقد أذهلني كيف يمكننا محاكاة الظواهر الفيزيائية ببضعة أسطر من التعليمات البرمجية.
With this rich simulation, you can visualize and measure the phase difference between two sound waves using two microphones connected to an oscilloscope. Moreover, you can determine the speed of sound in air by measuring the distance between the two microphones when their waveforms are in phase, taking into account the frequency of the sound wave that is controlled by the sine wave generator.
This is a new simulation of a rotating disk being illuminated by a stroboscope. You can control the speed of the disk and the frequency of the stroboscope, and see how the white spot on the disk appears. You can check all the cases of stationary appearance and the slow-motion appearance.
This experiment demonstrates Archimedes’ principle and buoyancy. When an object is placed in a liquid, it displaces a quantity of liquid with mass equal to the object’s mass. The volume of displaced liquid equals the volume of the immersed part of the object. A fundamental demonstration of fluid mechanics and displacement principles.
يوضح هذا الدرس مفهوم عزم الدوران (عزم القوة) والتوازن الدوراني. تُحدث القوة تأثيراً دورانياً يعتمد على مقدار القوة والمسافة العمودية من نقطة المحور. عند التوازن، يساوي عزم الدوران في اتجاه عقارب الساعة عزم الدوران عكس عقارب الساعة. يتضمن المنشور معادلات حساب عزم الدوران للقوى العمودية والمائلة.
Inertia is the property of matter that resists changes in velocity. When a car brakes, your body leans forward; when it accelerates, you lean backward – both demonstrate inertia in action. The greater your body’s mass, the more pronounced this effect. Inertia encompasses resistance to changes in both speed and direction of motion, making it a fundamental concept in understanding how objects behave.
