What happens when you double the amplitude of the spring mass system?

This video explores the fascinating topic of energy in a hanging spring system. The video starts with a question: What happens when you pull a spring twice as far to start it oscillating? Dr. Johnson then delves into the mechanics of the system, consisting of a hanging spring with a mass attached. Using a graph to plot the displacement and velocity of the object, the professor explains the equations for position and velocity. The video also covers potential and kinetic energy, with clear explanations of the equations involved. One interesting aspect of the video is how it illustrates the relationship between potential and kinetic energy as a function of position. Starting from the maximum negative displacement, the potential energy drops to zero at the equilibrium position before increasing again to the maximum. In contrast, the kinetic energy is a flipped image of this, reaching a maximum speed and kinetic energy at the equilibrium position before slowing down again. The video also shows how energy scales with amplitude. Doubling the amplitude quadruples the energy required to move or stop the system, while tripling the amplitude increases the energy required even further. Overall, this video is a great introduction to the mechanics of hanging spring systems and the energy involved, presented in an accessible and engaging way. #apphysics #learnphysics #class11physics #oscillations
