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.
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.

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.
يوضح هذا الدرس مفهوم عزم الدوران (عزم القوة) والتوازن الدوراني. تُحدث القوة تأثيراً دورانياً يعتمد على مقدار القوة والمسافة العمودية من نقطة المحور. عند التوازن، يساوي عزم الدوران في اتجاه عقارب الساعة عزم الدوران عكس عقارب الساعة. يتضمن المنشور معادلات حساب عزم الدوران للقوى العمودية والمائلة.
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.
Newton’s first law states that when net force is zero, objects at rest remain at rest and objects in motion continue at constant velocity. This experiment uses an air cushion scooter to eliminate friction, demonstrating that with zero net force (weight balanced by track reaction), the scooter remains stationary when at rest and continues moving at constant speed when given an initial push, until an external force stops it.
