What Unit Results from Dividing Joules per Kilogram by Meters?

[Timothy Schablin]

What unit would i end up with if i divide 1 Joules/kg by .5 meters?

Would it be N/kg?

What is a Newton in terms of kg, m and s?

 

[Timothy Schablin]

ya. N/kg doesn't sound right. Its for finding the gravity on planet X. If the object has 1 J/kg of gravitational potential at .5 meters from the surface, what is the gravity on that planet?

So Vg = gy so g = V/y. So, 1/.5 = 2

The gravity on that planet is 2 m/s? But they want the answer in N/kg, but that doesn't sound right.

Re-arrange f=ma and what units do you get that equal N/kg?

Let me ask again. What is a Newton in terms of kg, m and s?
