When you walk across the carpet you pick up stray electrons. Those electrons then transfer from you to the doorknob when you touch it causing a shock.

Waves
The question is a little vague perhaps to make a very helpful answer. However, a very relevant example is to explain why if you push a cardboard box on a carpet why it doesn't just keep moving. The friction that is caused by the surface of the carpet and box cause the box to slow down and the energy that is lost (that you originally put into it by pushing it) is lost to heat that heats both the box and the carpet. Loss to heat is the most common form of energy loss.
Death
There can be a build up of static electricity on a car, especially on dry days. Static electricity is caused when electrons are knocked off when two objects rub against each other. The electrical charge is discharging itself to the Earth through you.You can get the same shock by dragging your feet across a nylon carpet and then touching someone; or rubbing a comb against your hair and putting it next to small pieces of paper; a plastic pen rubbed on your hair and then held close to a small stream of water will attract the water stream due to static electricity. Hair has to be clean and conditions have to be dry.

Carpet burns and their cousins, rope burns are caused by friction.
Static electricity may accumulate on an object, such as is caused by shuffling across a synthetic fibre carpet. Or as accumulates on a car body in a dry environment.
Thales of Miletus, a Greek philosopher, discovered that rubbing amber with silk created an electric charge in the amber which caused objects to be attracted to it. If rubbed enough, it created a spark, much like we receive when we walk on carpet and touch a doorknob and see, hear and feel the spark.
Mold is caused when a male ejaculates onto the carpet. When the carpet begins to get warm the sperm begins to set into the carpet in a fanominon caled mold. the more sperm that is ejaculated the more mold that thtere is going to be. yes
Carpet baggers
It wasn't quite at the end of the stage but carpet tacks were strune across the road atop of the final climb of the day causing many cyclists to suffer punctures.
Nobody knows what causes people to rub their feet on a carpet. Indeed,it may be different particles that inspire different people to do that. But allof the static electrical effects we see, including when they walk over to usand zap us, are due to the motion of electrons from one object to another.
The actor was so handsome that it caused several women along the red carpet to swoon.
The person who cuts across parking spots, it's illegal. If the parking lot is private property the damage caused in an accident is a civil matter not a legal one in most cases. Traffic laws do not extend to private property.
Glacial grooves are caused by the ice picking up boulders and scraping them across the bedrock.
