This energy can also produce macroscopic vibrations sufficiently lacking in randomization to lead to oscillations that are merely the exchange between elastic potential energy within the object and the kinetic energy of motion of the object as a whole.

Elastic Potential Energy If a force results in only deformation, with no thermal, sound, or kinetic energy, the work done is stored as elastic potential energy. Learning Objectives Express elastic energy stored in a spring in a mathematical form. Key Takeaways Key Points In order to produce a deformation, work must be done. Deformation can also be converted into thermal energy or cause an object to begin oscillating.
Key Terms deformation : A transformation; change of shape. Hooke's law is remarkably general. Almost any object that can be distorted pushes or pulls with a restoring force proportional to the displacement from equilibrium towards the equilibrium position, for very small displacements.
However, when the displacements become large, the elastic limit is reached. The stiffer the object, the smaller the displacement it can tolerate before the elastic limit is reached. If you distort an object beyond the elastic limit, you are likely to cause permanent distortion or to break the object. The elastic properties of linear objects, such as wires, rods, and columns which can be stretched or compressed, can be described by a parameter called the Young's modulus of the material.
This is an equation relating magnitudes. All quantities are positive. Young's modulus is a property of the material. It be used to predict the elongation or compression of an object before the elastic limit is reached. Consider a metal bar of initial length L and cross-sectional area A. The Young's modulus of the material of the bar is Y. Find the "spring constant" k of such a bar for low values of tensile strain.
How much would such a string stretch under a tension of N? Consider a point object, i. If this object is at rest and the net force acting on the object is zero, the object is at an equilibrium position.
