Draw a graph showing the variation of K.E and P.E with respect to displacement for a spring mass system.

Answer» <html><body><p></p>Solution :Let us consider the nature of a compressed or extended spring. A compressed or extended spring will transfer its <a href="https://interviewquestions.tuteehub.com/tag/stored-7260220" style="font-weight:bold;" target="_blank" title="Click to know more about STORED">STORED</a> potential <a href="https://interviewquestions.tuteehub.com/tag/energy-15288" style="font-weight:bold;" target="_blank" title="Click to know more about ENERGY">ENERGY</a> into kinetic energy of the mass attached to the spring. The potential energy-displacement graph is shown in the figure. It <a href="https://interviewquestions.tuteehub.com/tag/shows-1206590" style="font-weight:bold;" target="_blank" title="Click to know more about SHOWS">SHOWS</a> variation of potential energy with respect to displacement. <br/> In a frictionless environment, the energy gets transferred from kinetic to potential and potential to kinetic repeatedly in such a way that the total energy of the system remains <a href="https://interviewquestions.tuteehub.com/tag/constant-930172" style="font-weight:bold;" target="_blank" title="Click to know more about CONSTANT">CONSTANT</a>.
