Because without friction static electricity can't exist. As the friction occurs it builds up the potential in anything with any kind of capacitence until you give it a path to ground (i.e..your light switch or metal plate). That's when you get your telltale "snap". Hundreds even thousands of volts can be built up. No amperage however, otherwise our lives would be endangered every time we drug our feet across the carpet in slippers :)
By adding or losing eletrons (friction)
Friction generates static electricity by causing two surfaces to rub against each other, stripping away some of the electrons from one surface and depositing them onto the other surface. This creates an imbalance of positive and negative charges, resulting in static electricity buildup.
When two surfaces rub against each other, friction is generated. This friction produces heat and wears down the surfaces over time. In some cases, it can also create static electricity.
Some fibres do not contain moisture are are 'dry', static develops when fabrics made from 'dry' fibres are subjected to friction
Some people may accumulate more static electricity due to factors such as the materials they come in contact with, the humidity of their environment, and their clothing choices. Factors like friction and insulation also play a role in a person's tendency to build up static electricity.
During solving the questions (In Physics) sometimes we consider the bodies frictionless but friction exists. : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : sorry mom calling(:P)
The friction between the tires of a car and the road surface helps the car to grip the road and not skid. The friction between your shoes and the ground helps you to walk or run without slipping. The friction between the strings and frets of a guitar allows you to play different notes by pressing down on the strings.
The best conductor of electricity is Silver, while the best conductor heat is helium (in its Helium II state), but some people consider diamond as the best heat conductor.
Some common questions about friction that are frequently asked include: What is friction and how does it work? What factors affect the amount of friction between two surfaces? How can friction be reduced or increased? What are the different types of friction?
Some types of electricity is static electricity, current electricity...and porn.
Friction is often seen as a hindrance to motion because it opposes the movement of objects by creating resistance. It can slow things down, decrease efficiency, and cause wear and tear on surfaces in contact. While friction is necessary for many everyday actions, excessive friction can be considered undesirable in some situations where smooth, unhindered motion is desired.
