==Monocoque==
:See Chassis
==Motor Generator Unit - Heat==
Also known as MGU-H, it is one of the six components of the power units. The MGU-H uses the hot exhaust flowing through the turbocharger to generate power, which can be stored in the Energy Store (ES), essentially charging batteries. The process can also be reversed at times of low RPMs, when the MGU-H acts as a motor to spin up the turbocharger, thus greatly reducing throttle lag.
==Motor Generator Unit - Kinetic==
Also known as MGU-K, it is one of the six components of the power units. The MGU-K is directly connected to the crankshaft of the ICE, thus is charging the Energy Store (ES) via kinetic energy. The process is often reversed under acceleration, boosting power output, and in emergencies this unit can act as a starter motor.
----

==Parc fermé==
The term "parc fermé" originates from the French language, literally translating to a "closed park."
==Pit board==
A board held out from the pit wall to tell drivers their position, the time interval to the car ahead or the one behind and the number of laps of the race remaining.
==Pit wall==
The wall that separates the pit lane from the track. This is also where team managers, owners and engineers spend their race, monitoring data and planning strategy.
==Pits==
An area of track, usually located near the start/finish line, where drivers receive service to their car. The team garages are also located in this area.
==Plank==
A wooden strip that is attached to the underside of cars during test and practice sessions. This helps team engineers to ensure that the car is not running too low to the ground.
==Podium==
The area at which the top three finishing drivers receive their prizes.
==Pole Position==
The first position of the grid. This is usually given to the driver that posted the fastest lap during the third round of qualifying.
==Porpoising==
Porpoising is a phenomenon where the cars bounce up and down on the straights at high speed. This is caused by the design of the new 2022 cars being mostly dependent on "ground-effects", which makes use of a three-dimensional floor to create downforce. As the car's speed increases, the aero devices in the car's floor pulls it down and compresses the suspension. As this compression reaches a point where it reduces the airflow under the car, the effects of the downforce will be reduced, which causes the car to lift back up. This cycle repeats itself, which is described as porpoising. Porpoising negatively affects the balance of the car making it difficult for drivers to control the car and it also causes vibrations, which limit the drivers' visibility; teams are actively seeking for solutions to the issue.
==Power Unit==
The group of devices that generate power in the car. It is comprised of six components: the Control Electronics (CE), Energy Store (ES), Internal Combustion Engine (ICE), Turbocharger (turbo or just "T"), Motor Generator Unit - Heat (MGU-H) and Motor Generator Unit - Kinetic (MGU-K).
==Powertrain==

A high ranking official appointed to make decisions at each Grand Prix event. Learn more about what they do and how they are chosen at this AutoSport article.
==Stop-go penalty==
A penalty that requires drivers to return to their pit and stop before rejoining the race. Sometimes the penalty requires a driver to wait for a period of time before moving. The penalty duration is determined by the race stewards depending upon the severity of the rule violation.
==Super License Penalty Points==
As of the 2014 season, a penalty points system has been implemented whereby a driver may be given between one and three penalty points by stewards for various infractions. These penalty points accumulate but expire one year after they were earned. Any driver who accumulates twelve penalty points within a year will face a one race ban.
