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.
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.
I updated the graphical user interface for easier interaction and better fitting in the browser. I also optimized the code.
This simulation is 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.
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.
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.
