# What factors determine elastic energy?

The kind of material and the degree to which it is distorted are two factors that influence the quantity of elastic potential energy stored. The more an item is distorted, the more energy it has stored. Energy is also lost as heat when a body changes phase or becomes rigid.

Elastic energy is released when a force is removed from a stretched string or rubber band. The string will return to its original shape and store additional energy until it is relaxed by being pulled too tight or overstressed.

Elastic energy is recovered when a load is removed from a compressed spring. The spring will expand back to its original size and release its energy in the form of kinetic energy.

Energy is not destroyed but transformed from one form to another as waves vibrate air molecules or heat melts ice cubes. Energy is still present but in a different state. It is difficult or impossible to recover all of this energy so some of it is lost.

Elastic energy is energy that can be recovered later when it is needed. It may be used to lift heavy objects or run motors without using fuel.

In physics and engineering, strain is the amount by which a material is distended or stretched. Strain can be divided into three types: pure strain, thermal strain, and mechanical strain.

## What do you need to do to an object to give it elastic potential energy?

Elastic potential energy is the energy that is stored as a result of exerting force to deform an elastic object. The energy is held until the force is withdrawn, at which point the item returns to its previous shape while performing work. The item might be compressed, stretched, or twisted as a result of the deformation.

You can transfer elastic potential energy from one object to another. For example, if you stretch a rubber band and let go of it, it will return to its original length while storing potential energy. You can use this energy to do work by pulling it again. Or, if you wanted to light something up, you could release the rubber band's energy by letting it snap back into shape.

Things you need to know about elastic potential energy:

Elastic potential energy is the most common form of potential energy. It is stored in objects that have been deformed by external forces (such as tensioners in springs), vibrated (like guitar strings), or rotated (like door knobs). Elastic potential energy is released when the force causing deformation is removed; for example, when the string is let go or the drumhead is struck. This energy can then be used to do work by pulling on the string or hitting the drum.

External forces are needed to produce elastic potential energy, and these forces must be removed to do work with it. For example, suppose we have a spring with mass attached to it.

## What energy is used to stretch?

Potential energy that is elastic Elastic potential energy is the energy stored in things as a result of tension (such as a stretched rubber band) or compression (when you squeeze a spring). Potential energy is turned to motion energy, also known as kinetic energy, when it is "released." When the rubber band is released it will stretch out and become less tense which reduces its potential energy, turning it into kinetic energy.

When an object moves from a state of rest to one of constant velocity, its kinetic energy increases by \$mgh\$ where \$m\$ is its mass, \$g\$ is its acceleration due to gravity and \$h\$ is its height above a horizontal surface. If we assume that the object is not moving too far away from free fall, then \$a = -g\$. So the increase in kinetic energy is equal to \$-mgx\$, where \$x\$ is the distance the object has traveled.

The work done by gravity on an object is equal to the change in its kinetic energy. So we can say that \$\Delta K = -mg\Delta x\$, where \$\Delta K\$ is the change in kinetic energy and \$\Delta x\$ is the change in position. This equation shows us that to stretch something, we need to do work against gravity. Energy is needed to stretch the thing.

Gravity acts on all objects at the same rate.
