The animation illustrates the principle of Fourier synthesis: Complex periodic waveforms can be generated by superposition of simple sine waves (harmonics). The number of harmonics and the target waveform are adjustable. Links Description of the Animation The animation visualizes the Fourier series, which allows periodic functions to be represented as a sum of sine functions:… Read More »
The animation simulates the physical behavior of ice cubes in a glass of water. By clicking or using a button, ice cubes can be created that fall into the water, submerge, and float to the surface due to buoyancy—an illustrative example of Archimedes’ principle. Links Description of the Animation The animation shows a glass filled… Read More »
The animation simulates the gravitational force between celestial bodies. Planets with different masses and initial velocities attract each other, form orbits, and can merge upon collision – an interactive model for exploring Newtonian gravitation. Links Description of the Animation The animation shows a space with freely placeable planets that attract each other according to Newton’s… Read More »
The animation simulates a billiard shot to demonstrate the law of conservation of momentum. A white cue ball can be aimed at colored object balls, with the collisions showing momentum transfer between the balls. Links Description of the Animation The animation shows a billiard table with a white cue ball and six colored object balls… Read More »
The animation illustrates the relationship between circular motion and a harmonic wave. A rotating pointer in the circle generates a sinusoidal wave curve through its projection—a fundamental principle for understanding oscillations and waves. Links Description of the Animation The animation shows how uniform circular motion and harmonic oscillation are mathematically related. A point moving at… Read More »
