Physics Zone’s complete collection of interactive physics and math simulations, built with HTML5 for modern browsers.
A free interactive single-channel virtual oscilloscope simulation for intermediate physics classes. Connect a function generator or DC source and observe sine, triangular, and square waveforms in real time with adjustable frequency and amplitude.
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.
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.
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.
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.
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.
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.
Use this interactive simulation to visualize the phase difference between two sound waves on an oscilloscope. Measure the microphone spacing and frequency to calculate the speed of sound in air.
Experiment with the refraction of light as it passes from air into a transparent semi-disk. Choose different materials and apply Snell’s law to determine the index of refraction based on your measurements.
Explore the photoelectric effect with this advanced simulation. Graph photocurrent vs potential and intensity, and kinetic energy vs frequency. Adjust parameters, visualize results, and discover key quantum physics relationships interactively.
