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.
توضح هذه التجربة مبدأ أرخميدس والطفو. عند وضع جسم في سائل، يزيح كمية من السائل تساوي كتلتها كتلة الجسم نفسه. كما أن حجم السائل المُزاح يساوي حجم الجزء المغمور من الجسم. عرض أساسي لمبادئ ميكانيكا الموائع والإزاحة.
تُظهر هذه التجربة في انعدام الجاذبية على متن مكوك فضائي قانون نيوتن الثاني. بدون قوة الجاذبية، يطبق رائد الفضاء نفس القوة على كرات ذات كتل مختلفة. تتسارع الكرة الأخف أكثر من الأثقل، مما يثبت العلاقة العكسية بين الكتلة والتسارع عندما تكون القوة ثابتة (القوة = الكتلة × التسارع). عرض مثالي لمبادئ الفيزياء الأساسية في ظروف الجاذبية الصغرى.
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.
