Mit welchem Buchstaben wird Geschwindigkeit Abgekürzt?

Huhu,

mein Physiklehrer meint, Geschwindigkeit wird mit einem „V“ abgekürzt. Jedoch steht im Buch ein „v“. Im Internet steht irgendwie beides, jedes mal ein anderes Ergebnis.

was davon ist nun richtig? ^^“

danke im Voraus

A small v is common for speed.
A large V is customary for volumes, and U or V is also suitable for potential energy.

Note that you have to do it at speed with a vectorial size. Therefore, the v is often printed with an arrow on it or bold.

In formulae, small letters are usually used.

Little v is right. Large V is usually the volume.

“correct” is always the symbol that is associated with the physical size in the context of a task or publication, for example “an auto moves with the speed v …”

There are no overcrowding symbols except in the head of teachers who always use the same symbols and are too lazy for the context description.

Small v is correct

It is a small v. The big V is the voltage.

Formula characters and characters for a unit have nothing to do with each other.

I know, but forgot the V for the tension in the German is unusual. In English-language texts this is actually found as a formula mark.

No. V is the short form for volts, the INHEIT of the electrical voltage. Topic missed.

No, much more recently read in English, where the V is also used as a formula for tension.

Voltage would be “u”

U, if so 😉

Thank you, I don’t need to googlen.

You can see how little you use the reading. For this purpose, the large U is used for the voltage, the R for resistors and the I for current strengths. Ohmsh’s law.
