This experiment shows that, when placed in a liquid, the object displaces a quantity of liquid of mass that is equal to the mass of the object itself. Moreover, the volume of the displaced liquid is equal to the volume of the immersed part of the object.
لو تم إجراء هذه التجربة في ظروف يكون فيها صافي القوى الخارجية صفرًا على المدفع المُحمّل قبل وبعد إطلاق النار مباشرة (على سبيل المثال، عندما يكون وزن المدفع متوازناً مع رد الفعل العمودي للأرض)، فإن حسبنا عندئذٍ حاصل ضرب كتلة القذيفة بسرعتها المتجهة وحاصل ضرب كتلة المدفع بسرعته المتجهة قبل وبعد الإطلاق مباشرة، سنجد أنه قبل إطلاق النار كان كلاهما في حالة سكون، وبالتالي يكون الناتج صفرًا لكليهما، بينما نجد أن الناتجين، بعد إطلاق النار ذوا مقدار متساوٍ، ولكن باتجاهين متعاكسين.
Given the accelerated development of AI, there might soon be a ‘Super AI’. And I am not talking about an AI with super faster processing or super deeper analysis. I am talking about an AI that may develop a form of “perception” fundamentally different from human ways of perceiving reality. To us, its view of the world may appear almost metaphysical.
A useful simulation for the students in their studies and for the physics teachers in their presentations of electricity lessons.
The simulation includes alternating generators (AC) and direct generators (DC).
In this simulation, the oscilloscope can display waves coming from generators similar to the real ones.
Newton’s second law states that net force and acceleration are directly proportional, with mass as the constant of proportionality (F=ma). This experiment uses an anvil supported by air pressure to demonstrate that even when weight is counteracted, the anvil’s huge mass still requires enormous force to accelerate it from rest. A powerful illustration of the relationship between force, mass, and acceleration.
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.
The probe waveform display in Interference of Waves Simulation now renders mathematically perfect sinusoidal waves, making phase relationships and superposition easier to observe and more reliable as a teaching and learning tool.
