for newton's laws, do you refer to acceleration as m/s^2 or N/kg?

Best ResponseYou've already chosen the best response.0don't you use N/kg for gravity also?

Best ResponseYou've already chosen the best response.0yes gravity is just a special type of acceleration.

Best ResponseYou've already chosen the best response.0so in newton's laws, you go for a=N/kg instead the m/s^2?

Best ResponseYou've already chosen the best response.0yes because m/s^2 is just units. whereas N/kg is actually a variable representation of acceleration.

Best ResponseYou've already chosen the best response.0is 1 N/kg equal to 1 m/s^2?

Best ResponseYou've already chosen the best response.0wait actually I'm sorry for some reason I was thinking F/m. both are units that mean the same thing.

Best ResponseYou've already chosen the best response.0so really use can use either to represent accleration, but typically we use m/s^2 to represent acceleration.

Best ResponseYou've already chosen the best response.0For Newtons second law the units would be m/s^2

Best ResponseYou've already chosen the best response.0is this for a homework question or are you just trying to understand units better?

Best ResponseYou've already chosen the best response.0understanding the units, because im not sure what units to put after i find the acceleration?

Best ResponseYou've already chosen the best response.0N/kg is odd, butt yes it means the same thing.

Best ResponseYou've already chosen the best response.0think about velocities unites, we use m/s for velocity, so to keep it consistent use m/s^2 for acceleration.

Best ResponseYou've already chosen the best response.0See if you look at g as acceleration due to gravity.. then you normally use m/s^2.. cause even if its acceleration due to gravity.. its none the less acceleration and that has to be its SI units.. However.. there is another TOTALLY DIFFERENT way to look at g.. and that is called as gravitational field intensity.. .meaning.. how strong is the field of gravity due to earth (or for that matter any mass).. when you mean THAT way.. you usually say g = N/kg.. meaning you are saying.. how much force a UNIT mass would experience in a gravitational field... so bottom line if i said g = 9.8m/s^2... it basically says how much acceleration i would get at that point .. if i said g = 9.8 N/kg.. it means how much force is experienced by a unit mass kept at that point.. so even though they have the same physical dimensions.. they are two VERY different concepts!! and hence we use those different units!

Best ResponseYou've already chosen the best response.0First thing: there is no difference between N/kg and m/s², so both are ok. Acceleration is a kinematic concept in the first place. So it is more logical to use m/s² Even if N's 2nd law did not exist, and the unit newton had not been defined, you could still work with accelerations in m/s². When you first encounter g, it is seen as the ratio of a force by a mass as you hang a mass on a spring, so it is logical to use N/kg to define it. But then you realise an object in free fall has an acceleration equal to g as well, and then the natural unit becomes m/s². It is the same with other quantities, and it is sometimes a cultural point of view. In France, all electric fields are given in V/m, but I think I have seen a different (but same) unit on this forum, though I cannot remember which one it was, maybe N/C.
