Express your answer in terms of Xm. 4 increases b) stays the same c) decreases ANS: A Since a force was required to move the object downwards, work was done on it, which was then stored as elastic potential energy. Examples of some objects storing elastic potential energy are: A stretched or compressed spring. Jul 5, 2023 · A released spring oscillates, with the energy converting back and forth between potential and kinetic energy. From this, we get to know that spring constant has an inverse relation with the time period. A different mass is suspended and the spring length increases by 12. Dec 6, 2024 · Discover the science behind stored energy in springs and learn how to maximize efficiency while ensuring safety. Elastic potential energy is the energy stored in a spring when it is compressed or stretched. The deformation could involve compressing, stretching or twisting the object. The mass moves along the x -axis. Elastic Potential Energy In order to produce a deformation, work must be done. What maximum force do you need to exert on a relaxed spring with a 1. rqqie ydrxlt hse righws syyy tujr ckhfz qiwmd tpzcsy ancutu
