Friction.
Charging by rubbing, also known as triboelectric charging, is a process where two different materials are rubbed together, causing a transfer of electrons between the materials. This transfer of electrons results in one material becoming positively charged and the other becoming negatively charged.
Two surfaces are rubbing together to create friction. The friction is the force that resists the motion between the two surfaces and can generate heat.
Examples of two objects that rub together include rubbing a balloon against fabric to create static electricity or rubbing two sticks together to start a fire.
The amount of static charge produced when you rub two things together is affected by the materials' triboelectric properties (their tendency to gain or lose electrons) and the surface area in contact during rubbing, which influences the transfer of electrons between the materials.
Sticks rubbing together is an example of friction, a force that opposes the motion of two surfaces in contact. When sticks rub together, the friction between them generates heat and can produce sparks, which is why rubbing sticks together is a traditional method for starting fires.
Static
Rubbing two materials together can transfer electrons from one material to the other, resulting in one material becoming positively charged and the other becoming negatively charged.
Charging by rubbing, also known as triboelectric charging, is a process where two different materials are rubbed together, causing a transfer of electrons between the materials. This transfer of electrons results in one material becoming positively charged and the other becoming negatively charged.
Rubbing certain materials together creates static electricity. This occurs when electrons are transferred from one material to another, resulting in a buildup of electric charge.

When two materials are rubbed together, it can cause a transfer of electrons between them, resulting in a build-up of static electricity. This can lead to various effects such as a spark discharge, attraction or repulsion of objects, or even a mild electric shock.
