Yes - it's still a rubber band.
Yes - it's still a rubber band.
It has potential to do work. Looking at it another way, it requires energy to stretch the rubber band; this energy can be recovered - for example, by pulling something - when the rubber band gets back to its normal position.
You can give the rubber band potential energy by stretching the rubber band, however if you let it go and it moves then it will no longer be potential energy.
Yes
Stretching a rubber band is a physical change.

Rubber is elastic. After streching is stopped, it will regain its shape.
Elastic potential energy.
Yes
chemical energy example, car battery, food, fuel Stored mechanical energy example, stretching or compressing a spring or rubber band
Stretching the rubber band would lengthen it. It is the sentence containing the lengthen word.
No. The rubber band stores energy as elastic potential energy. U = (1/2)*k*(L)^2 where, U is the stored energy k is the spring constant for the rubber band L is the displacement
