Équation différentielle: oscillateur harmonique amorti 11/26

Within the framework of classical point particle and rigid body mechanics taught in Physics I at the Swiss Federal Institute of Technology Lausanne (EPFL), we propose to explore some mathematical concepts relevant to your physics practice: an example of a differential equation where a mass-spring system is subject to a viscous friction force. This is a damped harmonic oscillator, and the solution to the equation of motion, after treating the problem as a quadratic equation, reveals a decreasing exponential function, indicating a decrease in the amplitude of the oscillations. This video is part of a series of videos produced for the Uniknow mobile app, which will help you review the theoretical content of your first university physics course while practicing your knowledge through multiple-choice questions (MCQs). It will be available on the App Store and Google Play starting September 18, 2018. Link to Uniknow on the App Store: https://itunes.apple.com/us/app/unikn...
