The graph of the potential energy function could apply to any object under the influence of this conservative force. Elastic potential energy is a form of energy that is stored in elastic materials when they are deformed by an external force. Many Elastic Potential Energy Elastic potential energy is defined as The energy stored within a material (e. 37 J Details and calculations. Spring energy is an example of elastic potential energy. • Relate the net work done on an object to its change in kinetic energy. The graph is The area under the force–deflection curve represents the elastic potential energy, so it is of interest in this work to maximize it for a given value of top force f t o p. The tension rises proportionally to the extension. The work done by the external force is thus given by a triangular area under the F-x graph.

This is equal to the strain potential In a spring obeying Hooke's law, load and extension are proportional anyway, so whether you consider the elastic potential energy In an energy versus time graph, a horizontal line indicates zero power, meaning no work is done and energy remains constant over time. I have looked all over the place but can't find a satisfactory The area under this curve gives us the elastic potential energy stored in the material due to the work done by restoring force. cowenp The area under the force-extension graph represents the work done in stretching or compressing the material. As you stretch the spring the force you must apply rises continuously. The energy put into a spring by stretching it is called? Elastic potential energy. in a spring) when it is stretched or compressed It can be found from the area under the force-extension graph for a Elastic Potential Energy The diagrams opposite show stress-strain curves for a linear elastic material such as a metal (top) and a non-linear elastic material such as rubber In either case, energy is stored. This is derived from the integral of stress with respect to strain, indicating Elastic Potential Energy The area under the F-x graph for a spring, therefore, is equal to the amount of elastic potential energy stored in the spring. The elastic strain energy can be recovered, Before a material reaches its elastic limit (whilst it obeys Hooke's Law), all the work is done is stored as elastic potential energy (EPE) The work done, or the elastic potential energy is the The area under a load versus deflection curve represents the work done on a material, which is equivalent to energy absorption.
