I will keep a simplified discussion here!
First thing to understand is that cars’ speeds are limited by gear ratios chosen for different circumstances. Car can't go faster that gear ratio alove him to go.
A short gear will result in higher torque but a lower top speed.
A long gear will result in lower torque but a higher top speed.
With that in mind, F1 engineers tune F1 gars for each track separately. Again finding the right gear ratio for a F1 car on new track, need a bit of a testing, simulation and experience. On well known track, F1 engineer use data from previous events.
If revs are not reaching the redline at the end of the straight, they can shorten the gears, until they find the revs just reaching the redline. If they find that revs are going up too quickly on a faster part of the track, that normally mean that on slower curvy part of the track they do not have enough power on the wheels. Adjusting a gear ratio is always a compromise between speed and torque.
Numbers of teeth on mating gears is caled gear ratio. Ordinarily the ratio is found by dividing the number of teeth on the larger gear by the number of teeth on the smaller gear or pinion. For example, if the ratio is 2 or "2 to 1", this means that the smaller gear or pinion makes two revolutions to one revolution of the larger mating gear.

Master gears |
The smallest gear of a gear drivetrain is called pinion. The pinion can be either the driving or the driven gear and is often used in cars as differential pinion or in a rack-and-pinion steering mechanism.
