I Unit when using J/kg by m

  1. Jul 6, 2017 #1
    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 doesnt 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 doesnt 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?
