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.

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.
This interactive wave interference simulation demonstrates the fundamental principles of wave superposition using two sources. Users can adjust key parameters including wavelength, amplitude, phase difference, and source separation to observe how waves interact and produce complex interference patterns. The simulation features a real-time probe tool that displays individual wave amplitudes and their resultant superposition, showing constructive and destructive interference at different points in the field. The visual representation includes radiating wave fronts from both sources, with characteristic alternating bands of high and low amplitude clearly visible throughout the interference pattern.
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.
A new simulation, that simulates the free fall of an object (ball). This simulation gives the ability to measure the acceleration of gravity by taking successive shots of the falling object with recording the time of each shot and measuring the coordinate y for each shot. It also enables us to check the famous free fall equation:
y = (1/2) gt²
