What Units should this be?

[TheDarkOne]

With tthe equation KE= 1/2mv^2 if I use KG for m and m/s for v sould I get KJ or just J? I think its KJ, but I'm not sure.

Since kilograms are the standard unit for mass (not grams), your output unit would be kg•m^2/s^2, which is defined as a Joule.

In case you're curious as to why physicists use kilograms (a modified base) instead of grams (a simple base), think of it this way. A quarter-pounder with cheese weighs about 1N using kilograms as the standard. If we used grams, a quarter-pounder with cheese would be 1000N! That sounds like a really weird scale, doesn't it? So, we use kilograms.

damn it, you see, this is the first time in about a year that I've done physics problems.

wait, doesnt a kg of mass weigh 1N?

See why you should have chosen engineering?

kg = unit of Mass

N = unit of Force

F = m*g => N = 9.81*Kg

1 Kg of mass exerts a gravitic force of 9.81 N

ee why you should have chosen engineering?

naaaaah. i do the design, you do the math, i get the money, i get the fame.

MAHOK!

But you don't get the Knoweledge

[salm]

not that knoweledge, but other knoweledge which other people dont get.

Mechanical Engineers build bombs

Architects build.. targets

good point!
