Simulations Now Load Faster!
All simulations have been updated to use a locally hosted CreateJS library instead of an external one, resulting in faster loading, smoother performance, and improved reliability.

Newton’s Tube Simulation
This simulation models Newton’s tube experiment, showing how air resistance affects falling objects. By removing air from the tube and flipping it, users can observe how a feather and a pebble fall differently in air but identically in a vacuum—demonstrating that gravity accelerates all objects equally when air resistance is removed.
Interference of Waves Simulation
This interactive wave interference simulation demonstrates wave superposition from two coherent sources. Users can adjust wavelength, amplitude, phase difference, and source distance to observe dynamic interference patterns. A real-time probe displays both individual wave amplitudes and their combined effect, illustrating constructive and destructive interference across the field.
A fix to the “Phase Difference Between Sound Waves Simulation”
In response to valuable feedback about the simulation “Phase Difference Between Sound Waves Simulation,” highlighting the slight inaccuracy of the obtained speed of sound of air, which was found to be about 349 m/s, this inaccuracy was fixed, so now it gives 346 m/s as it is supposed to give at room temperature.
Projectile Game
This physics-based game requires applying projectile motion equations to hit moving targets. Measure distances, set the angle, calculate the initial velocity, and hit the target across three increasingly challenging levels.
Fixes to the Stroboscope Experiment simulation
Since the frequency of the slow apparent motion in the stroboscope experiment varies depending on various factors that are not taken into consideration in the simulation, an essential change has been made to the code of the Stroboscope Experiment simulation to address the frequency of this apparent motion in the observation remarks.
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.

Area Model of Partial Products
This simulation demonstrates how to apply the distributive property using the area model of partial products. It breaks multiplication into smaller parts, then adds them to get the full product.
Long Division Simulation – Remainder
A comprehensive simulation that teaches long division with remainders step by step. Ideal for learners needing clear, guided practice. Also available: a version for float (decimal) quotients.
Long Division Simulation – Float
This simulation teaches long division with decimal (float) quotients through a clear, step-by-step interface. Great for learners who need guided practice. A version for remainder-based division is also available.
