![]() ![]() This is called the principle of superposition. The sum at any given point along the string is simply the sum of the displacements from equilibrium of each of the individual pulses at that point. When the two pulses overlap, their sum is shown on the bottom black string. This is a simulation of two wave pulses moving along the same string in opposite directions. Wave Pulse Interference and Superposition 2 Use the buttons to start or stop the animation. The sliders can be used to change the height and width of the pulses, as well as the animation speed. This is an animated simulation of the superposition of two waves pulses. This simulation allows students to observe the superposition of two wave pulses of varying height and width. Wave Pulse Interference and Superposition Each page has links at the bottom that lead you to the next (or previous) page in the tutorial. It incorporates many of the simulations listed separately in this menu, but also includes many animations and a lot of general information about waves. This is a multi-page tutorial on the basics of mechanical waves. This is a multi-step tutorial on Simple Harmonic Motion, showing derivations of the equations for position, velocity, acceleration, and period of an object in simple harmonic motion. After you check you answer you can create a new randomly selected graph and try again, over and over. From four other graphs of a different aspect of the object's motion, you must choose the one that matches the motion shown in the original graph. It can be a position, velocity, acceleration, or net force graph - each graph is vs. In this "quiz" you will be shown a motion graph for an oscillating object. Check or uncheck boxes to view/hide various information. Use the Run, Pause, Reset, and Step buttons to examine the animation. Adjust the initial position of the box, the mass of the box, and the spring constant. This simulation shows the oscillation of a box attached to a spring. This simulation is an exploration of the relationships between Simple Harmonic Motion, Uniform Circular Motion, and Transverse Wave Motion. Simple Harmonic Motion, Circular Motion, and Transverse Waves Select a simulation from one of the above categories or click on a category to see descriptions of the simulations for that category.
