When we rub two objects together then heat energy is generated.

Static Electricity!
Depends which 2 objects. Some do and some don't. (Try balloons on hair)

Gain or lose
Heat
the faster you rub them together, the smoothness or roughness of the objects, the air temperature.

ELECTRONS
These are electrically positive objects.
Static. and when you rub two objects together it will become warm or hot
When two materials rub together, the loosely held electrons of one material move to the material with the more tightly held electrons.
Whenever you use energy that is work, and to create friction work must be applied to rub two things together, and sometimes fast enough to create sparks depending on the two objects you rub together.
