Recoil.
The perimeter is also twice as large.
the change of shape of a metal at low temperature by loading and regaining of original shape by heating it,is known as shape memory effect
True
The shape of 2 right angles is a square.
Yes. Under translation the shape does not change, only the position of the shape changes - the translated shape is congruent to the original shape.
flammable, soft, malluble, spring like, returns to original shape when squshed
elastic
It can revert back to its original shape.
They are called smart shaped memory alloys they go back to their original shape when heated
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.
elastic
When a solid rock deforms and then returns to its original shape, it is known as elastic deformation. The rock doesn't break under pressure, but instead changes its form, and after the pressure is released the rock goes back to its shape.
A fluid that returns to its original shape after the applied stress is released
elastic
Anything which regains its original shape on removal of applied force.
As the ball returns to its original shape, kinetic energy decreases and potential energy increases.
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.
