One-Dimensional Elastic Collision Simulation
Using this simulation, you can demonstrate the conservation laws in a one-dimensional elastic collision (The law of conservation of linear momentum and the law of conservation of kinetic energy).

تجربة السقوط الحر
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.
A new publication based on the Virtual Oscilloscope simulation
The paper: Using a web-based and stand-alone oscilloscope for physics experiment during Covid-19 pandemic, Mahizah Ismail et al (2023), Phys. Educ. 58 015006, is based on the Virtual Oscilloscope simulation. This paper was authored by Mahizah Ismail, Farid Minawi, Wan Zul Adli Wan Mokhtar, Noraihan L Abdul Rashid and Ahmad K Ariffin.
The article DOI: https://iopscience.iop.org/article/10.1088/1361-6552/ac95ebConservation of linear momentum
This demonstration explains conservation of linear momentum through cannon recoil. When a cannon fires a bullet, it recoils backward with much lower velocity due to its greater mass, illustrating the inverse relationship between mass and velocity. The post provides complete mathematical derivations showing that total momentum remains constant in an isolated system where net external force is zero.
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.
Course: Crafting Effective Learning Objectives
I created this course and published it on my Moodle platform. Each module is a SCORM package, with a course evaluation survey at the end and an unofficial completion certificate as a template that can be costumed to the specifications of your organization. The course is tracked, and you must successfully complete each chapter to unlock the next one. The course is fully learner-centered.
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.
