توضح هذه التجربة أنه عند وضع جسم ما في سائل، يزيح الجسم كمية من السائل تساوي كتلتها كتلة الجسم نفسه. علاوة على ذلك، فإن حجم السائل المُزاح يساوي حجم الجزء المغمور من الجسم.

Stroboscope Simulation
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.
قانون نيوتن الثالث
يوضح قانون نيوتن الثالث أن لكل فعل رد فعل مساوٍ له في المقدار ومعاكس له في الاتجاه. يستخدم هذا الفيديو مشهداً من فيلم جاكي تشان لتوضيح المبدأ: عندما يدفع جاكي شريكه (قوة الفعل)، يختبر دفعة مساوية إلى الخلف (قوة رد الفعل)، مما يسمح لكليهما بالهروب من الخطر. مثال إبداعي من الحياة الواقعية على أزواج قوى الفعل ورد الفعل.
Torque
This demonstration explains torque (moment of force) and rotational equilibrium. A force can create a turning effect that depends on both the force magnitude and the perpendicular distance from the pivot point. At equilibrium, clockwise moments equal counterclockwise moments. The post includes formulas for calculating torque with perpendicular and angled forces.
How a 1-minute simulation changed my career path!
That moment stuck with me. It showed me how powerful simulations can be in breaking down complex ideas. It’s the reason I decided to learn how to develop science simulations to make learning easier for others.
Sometimes, all it takes is one moment to change your path!Photoelectric Effect Experiment Simulation
With this comprehensive and realistic-like photoelectric effect experiment simulation, you will be able to illustrate the following:
The variations of the photocurrent versus potential.
The variations of the photocurrent versus light intensity.
The variation of the kinetic energy of the ejected electrons versus the incident light frequency.
It comes with a graph where you can trace each type of variation as you vary the parameters of the experiment.
Plus, you can experiment and discover more with this simulation.Projectile Game
In this game, you must employ the projectile equations to win.
The game consists of three levels, each of which must be completed by scoring at least 8 out of a possible 10 tries. In the first level, you must hit a ground target that shifts position after each attempt. In the second level, you will need to alter the ball’s trajectory to pass over a wall. In the third level, the target flies and changes position both horizontally and vertically in each trial.
