من النتائج العجيبة لنظرية النسبية العامة أن الأجسام وبسبب المجال الثقالي (الجذبي) الناتج عن كتلتها (كمية المادة) تُقوّس نسيج الزمان-المكان (أو اختصارا الزمكان). وهذا التقوس لا يكون محسوسا بالقرب من الأجسام الصغيرة كأجسامنا، ولكنها تصبح ذات مقدار ملموس بالقرب من الأجسام الهائلة كالكواكب والنجوم.
وإذا خضنا أكثر في نتائج التقوس الزمكاني الذي تنبأت به نظرية النسبية العامة، وأخذنا بعين الاعتبار نجمين نراهما على أطراف كوكب هائل الكتلة، فإننا نرى كل واحد منهما منزاحا عن موقعه الحقيقي بحيث أن المسافة الظاهرية بينهما أكبر من المسافة الحقيقية. وبالتالي فإن المسافة بينهما قد تضخمت بمقدار ضئيل ربما نستطيع أن نتحقق منه بأعيننا المجردة أو بواسطة التليسكوب.
If you or your student or child are having difficulties in learning long division, then you will find this simulation comprehensive and instructional, that guides the learner through the process step by step. This application is for long division with remainder. Another application on long division with float quotient is also available in the simulations section.
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 story always reminds me how much work we still have to do in Lebanon to bridge the gap in technological literacy among educators!
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.
With this simulation, you can experiment the refraction of light between air and a transparent semi-disk. You can choose the material of the disk from a list of materials. Also, you can determine the index of refraction of the semi-disk when you apply Snell’s law to measurements you take in the simulation.
