25points derivea spring of spring constant K is attached to A block resting on a smooth horizontal surface. The Other end the spring is attached to a rigid wall the spring is light and massless. it is stretched to a displacement X. "find an expression for potential energy of the spring". |

Answer» The spring constant is the MEASURE of stiffness of a spring. Hooke's law gives us the force we need to find elastic potential energy. Looking at a graph of force VERSUS displacement, we can find that the FORMULA for elastic potential energy is PE = 1/2(kx^2). |
