Why does energy stored in deformed material in only its elastic portion?

The "elastic portion" is precisely the part where the material returns to its original shape, and thus returns its energy. Once the material does NOT return to its previous shape, it doesn't exert a force back to the original position, and there is no way to get the energy back.

Give one example of an object before and after it has gained elastic potential energy?
Elastic potential energy refers to the potential energy stored as a result of deformation of an elastic object. An example of this is a spring, which springs back before it has gained elastic potential energy. After a spring gains elastic potential energy, it will be deformed.
How do you convert elastic energy into electricity energy?
Elasticity is the ability of a material to return to its original shape after being deformed. It is not a form of energy. Mechanical energy is needed to deform the material which stores this partially as potential (mechanical) energy, some is transformed to heat energy, which dissipates, and some is lost to entropy, as in all energy conversions. When the potential (mechanical) energy is released it can be used to drive an electrical generator to produce electricity, until the material returns to its original shape.
What happens to the energy when two things collide?
the energy transfers from the moving thing to the stand still. The energy balance depends on whether the collision is elastic or not. If the objects involved are all elastic, ie not deformed permanently, there is no loss of energy. The easiest visualization is of a snooker or pool table, where the balls are elastic, the velocities before and after the collision are entirely predictable. However if the objects are deformed, energy is absorbed. A good case is cars colliding where they are designed to crumple to an extent, this makes the subsequent behaviour more difficult to calculate.
What happens when light strikes translucent material?
-- A portion of the light energy reflects back from the surface of the material. -- A portion of thelight energy is absorbed into the material and never seen again. -- The remainder of the light energy proceeds on through the material and emerges unbowed and undeterred from the other side.
What happen when light strikes a translucent material?
-- A portion of the light energy reflects back from the surface of the material. -- A portion of thelight energy is absorbed into the material and never seen again. -- The remainder of the light energy proceeds on through the material and emerges unbowed and undeterred from the other side.
The release of stored energy from rocks that are deformed by stress is called elastic?
shock
When a wind up alarm rings it a what source of energy?
Elastic energy. Elastic energy is released when a substance is deformed and then released so it can go back to its former shape.
How can you use elastic rebound in a sentence?
the rocks are deformed they break relasing the stored energy

Where does elastic energy come from?
The Elastic Energy is the energy of the molecular and/or atomic bounding forces - the structure of the material.
What kind of energy is stored in elastic material?
Thermal Energy
What type of material has elastic potential energy?
rubber

What are two examples of elastic potential energy?
very thin sheets of rubber are elastic
What are the 4 stages of elastic rebound hypothesis?
1) zero stress on elastic material/it's at original position 2) stress is applied/deformation occurs 3) release of energy (earthquake) 4) elastic material rebounds
