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.

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!

Inertia is the property of matter that resists changes in velocity. When a car brakes, your body leans forward; when it accelerates, you lean backward – both demonstrate inertia in action. The greater your body’s mass, the more pronounced this effect. Inertia encompasses resistance to changes in both speed and direction of motion, making it a fundamental concept in understanding how objects behave.

توضح هذه التجربة أنه عند انعدام مقاومة الهواء، يصل جسمان يسقطان بحرية من نفس الارتفاع إلى الأرض في نفس اللحظة. يكتسب كلا الجسمين نفس السرعة أثناء السقوط، مما يثبت أنهما يختبران نفس التسارع – تسارع السقوط الحر. تشرح التجربة سبب رؤيتنا للأجسام الثقيلة تسقط أسرع من الأجسام الخفيفة بسبب تأثيرات مقاومة الهواء.

Educational technology is more about strategically leveraging technology to enhance, transform, and even redefine teaching and learning than just merging education with technology. You have to be a strong educator equipped with learning theories, educational methodologies, and statistical analysis in the first place to be a successful educational technologist.

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.
