In summary, the conversation discussed finding the gravity on planet X using the equation Vg = gy and the rearrangement of f=ma to determine the units equal to N/kg. The conclusion was that the gravity on that planet is 2 m/s, but the answer should be in N/kg. The conversation also questioned what a Newton is in terms of kg, m, and s.

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?

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?
