I cant make a literature references about 'variable' in my title

[blackmage_nuke]

What is your favourite physical variable?

Im rather into acceleration due to gravity myself
Displacement is rather nice too, not distance though

[Tavrobel]

Force.

[Griff]

Speed

[rubah]

angular velocity (little omega)

[Resha]

Uh...time?

[Heath]

POWER

[Shlup]

Cranberry juice.

[The Unknown Guru]

I'm partial to inertia.

[Denmark]

can't go wrong with potential difference, better known to the world as voltage.

and are you sure acceleration due to gravity is a variable?

[Tavrobel]

and are you sure acceleration due to gravity is a variable?

Assuming that Mister _nuke here does his calculations on multiple planets/heavenly bodies, of course it is! Also, g changes based on where you are, above or below sea level, so it is technically variable, although I've only ever used it as the constant 9.8 m/s^2. Sometimes 10 m/s^2.

[Captain Maxx Power]

Gravity, because no one knows what the hell it is and what's causing it.

[Shoeberto]

g is a variable but G isn't

[ScottNUMBERS]

kickflip

[Zeromus_X]

[Bunny]

I'm going with Shlup on this one.
