Free Fall Simulation
A new simulation, that simulates the free fall of an object (ball). This simulation gives the ability to measure the acceleration of gravity by taking successive shots of the falling object with recording the time of each shot and measuring the coordinate y for each shot. It also enables us to check the famous free fall equation:
y = (1/2) gt²

Old Simulations
These simulations were made using the Adobe Flash/AcrtionScript. You can download them and run then in Windows.

Area Model of Partial Products
Elementary math teachers know the importance of this model in teaching the concept of applying distributive property in area model.
The idea is to break one large area (which represents the product of two numbers) into several pieces (products of smaller numbers), then to find the areas of the pieces individually, and finally add to get the area of the whole (the product of the given numbers).

Virtual Oscilloscope is Now Mobile-Friendly!
This time I have updated Virtual Oscilloscope so it is now mobile-friendly. Long-press any button, knob, or slider and it will scale up to become comfortable enough for your touch so you can control it comfortably using your mobile device.
I also optimized the code to perform smoothly on mobile devices.

Simulation Manual: Charging by Induction
A complete manual for the charging by induction simulation, including a short introduction and a user guide.

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.
