Can somebody tell me what m2 / s2 measures?? A square meter per squared second??

energy per unit mass!

what ever.
I ain't even important.

Measured? Nothing. But I suspect the question is really asking about what an energy equation means.

My guess is that it's the velocity component for 1 Joule of energy, 1 Joule = 1 kg m^{2} / s ^{2}, or kinetic energy of an object = 1/2 mass v^{2} (with v^{2} stated as m^{2} / s^{2} ). ... or it could be related to centripetal acceleration, a = v^{2} / r.

i'm sorry for necrobumping this old tread, but AM is actually right.
Using bernoulli's equations you can find out the loss of energy due to friction in joule/kg, which is the same as m2/s2. A joule is the same as a newton times meter, while a newton is the force required to accelerate a mass of 1 kg by 1 meter per second squared. so if you write it out it becomes: [itex]\frac{J}{kg}[/itex] = [itex]\frac{N*m}{kg}[/itex] = [itex]\frac{kg*m*m}{sē*kg}[/itex] =[itex]\frac{mē}{sē}[/itex] so m2/s2 could refer to the loss of energy per kg due to friction. It's used mostly in hydrodynamics and aerodynamics. Probably also in thermodynamics.
