Want this question answered?
Rubbing an insulator against a non insulator causes the build up of electrons which is known as static electricity, the electrons take the easiest route to earth, that's why if you touch any thing that is earthed you may get an electric shock :)
You 'scrape off' electrons from another material by rubbing both surfaces along/against each other. Electrons 'jump' over by this mechanical forces. (Wool, nylon, against plasics)
friction
the electrons get ripped off one object and held by the other The rubbing moves electrons to the object that holds them more tightly.
it is False.

Free electrons rubbing against each other creating energy

False. That's friction.
