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 the fundamental principles of wave superposition using two sources. Users can adjust key parameters including wavelength, amplitude, phase difference, and source separation to observe how waves interact and produce complex interference patterns. The simulation features a real-time probe tool that displays individual wave amplitudes and their resultant superposition, showing constructive and destructive interference at different points in the field. The visual representation includes radiating wave fronts from both sources, with characteristic alternating bands of high and low amplitude clearly visible throughout the interference pattern.
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.
In this game, you must employ the projectile equations to win.
The game consists of three levels, each of which must be completed by scoring at least 8 out of a possible 10 tries. In the first level, you must hit a ground target that shifts position after each attempt. In the second level, you will need to alter the ball’s trajectory to pass over a wall. In the third level, the target flies and changes position both horizontally and vertically in each trial.
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.
