WebThe relationship between the extension of an elastic object and the applied force is defined by Hooke's Law. Hooke's Law states that: The extension of an elastic object is directly proportional to the force applied, up to the limit of proportionality. Directly proportional means that as more force is applied, the greater the extension (and vice ... WebThe extension of the spring is determined by how much it has increased in length. The point is identified on the graph where the line is no longer straight and starts to curve (flattens out) Hooke’s law also applies to compression as well as extension. The only difference is that an applied force is now proportional to the decrease in length.

WebThe meaning of DEFORMATION is alteration of form or shape; also : the product of such alteration. WebThe energy is stored until the force is removed and the object springs back to its original shape, doing work in the process. The deformation could involve compressing, stretching or twisting the object. Many objects are designed specifically to store elastic potential energy, for example: The coil spring of a wind-up clock WebForces and elasticity are important concepts in many areas of science and engineering, such as mechanics, aerodynamics, and structural engineering.
