Newton’s third law
Newton’s third law demonstrates that for every action, there is an equal and opposite reaction. This video uses a Jackie Chan movie scene to illustrate the principle: when Jackie pushes his partner (action force), he experiences an equal push back (reaction force), allowing both to escape danger. A creative real-world example of action-reaction force pairs.
Phase Difference Between Sound Waves Simulation
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.
قانون نيوتن الأول
ينص قانون نيوتن الأول على أنه عندما تكون القوة الصافية صفراً، تبقى الأجسام الساكنة ساكنة والأجسام المتحركة تستمر بسرعة ثابتة. تستخدم هذه التجربة سكوتر بوسادة هوائية للقضاء على الاحتكاك، مما يوضح أنه مع القوة الصافية الصفرية (الوزن متوازن مع رد فعل السكة)، يبقى السكوتر ساكناً عند السكون ويستمر بالحركة بسرعة ثابتة عند دفعه، حتى تؤثر عليه قوة خارجية.

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.
Charging by Induction 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.
