This lesson covers Gravitational Potential Energy , Kinetic Energy and Elastic Potential Energy. It is equal to the work done to stretch the spring, which depends upon the spring constant k as well as the distance stretched. The gravitational influence on a body at infinity is zero, therefore, potential energy is zero, which is called a reference point. Formula ; According to Hooke's Law, Elastic potential energy is the energy saved in an object that is stretched, compressed (compression is pressing objects together), twisted or bent. But the value of Young’s Modulus is mostly used. The difference between elastic potential energy compared with kinetic energy or gravitational potential energy is that when you start stretching an elastic band or a spring, it is really easy to extend it, but the more you stretch the harder it becomes and the more force you need to exert on it (assuming you never break or deform it). ¿Cuál existieron simultáneamente es decir al mismo tiempo? We can compute Elastic potential energy by using fundamental formula as below: Elastic potential energy = force $$\times$$ displacement. In this article, we will discuss its concept and Young’s Modulus Formula with examples.
