heat will do it
Yes, it is, as long as you do not stretch it too much that it permanently deforms. Hooke's law states that extension is proportional to force, as is the elastic band.
It doesn't
If a pulling force is exerted on an elastic band, then the elastic band will stretch. The more force that is exerted, the more the band will stretch.
If you stretch a rubber band then release it, it will return to its original shape. That is by definition elastic strain. Anything that returns to its original shape after being affected by force underwent elastic strain. If it is permanently deformed (ie you bent a paperclip out of place and it wont return to its original shape) then it passes the elastic strain region and suffered plastic strain.
It is similar to elastic
Elastic potential energy
the weight
Elastic fibers made of the protein elastin has a coiled structure which allows it to stretch and recoil. Fibers can stretch up to 150 percent of their relaxed state length without breaking.
Elastic energy is also called Elastic Potential energy. It is the potential energy stored as a result of a deformation of an elastic object such as a spring. According to Hooke's law the force required to stretch the spring will be directly proportional to the amount of stretch.
Weight causes the elastic material to stretch. The material may be stretched beyond its elastic limit. If this happens, then the material rips or tears, or it does not return to its original size.
