First time poster. I'm in thermo this year and it's the first time working with pascals and joules. My teacher and most post just jump right into the equations, 1Pa = 1N/m^2 and 1J = 1N * M. But what really is a pascal? I get what a N is, force to move 1kg*m/s^2. If I convert N, I get 1Pa = (1kg*m/s^2)/m^2.

Solving further I get 1Pa = 1kg/s^2*m (1m on top cancels 1m on bottom, if I recall algebra correctly).

Can someone please explain what that means, in terms of a sheet of metal or something?

Same with a joule, convert N and its 1kg*m^2/s^2.

When I see something ^2, I immediately think "Ok, this is 2d we are talking about over the surface of a meter^2 ect.", same with ^3 "Ok, this thing has a volume in 3d space we are talking about". It's just how my mind seems to think about it.

Sorry if I'm approaching this wrong or should think of a N more abstractly. I just like to understand things better in 3d/2d algebraic sense and physics is based in that. Can anyone explain those 2 in context or real world? I just hate plug and chug, not knowing really what I'm "saying" to myself with a final answer.

Thanks,
