Discussion Overview

The discussion revolves around the unit resulting from dividing Joules per kilogram by meters, with a focus on gravitational potential energy and its implications for calculating gravity on a hypothetical planet. The conversation includes technical reasoning and unit analysis.

Discussion Character

  • Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions the resulting unit from dividing 1 Joule/kg by 0.5 meters, suggesting it might be N/kg.
  • Another participant seeks clarification on the definition of a Newton in terms of fundamental units (kg, m, s).
  • A participant expresses doubt about the appropriateness of N/kg in the context of calculating gravity on a hypothetical planet, proposing that if an object has 1 J/kg of gravitational potential at 0.5 meters, then gravity could be calculated as 2 m/s.
  • There is a challenge to re-arranging the equation f=ma to explore what units would equal N/kg.
  • A repeated inquiry about the definition of a Newton in terms of kg, m, and s is made, indicating a desire for clarity on the foundational units involved.

Areas of Agreement / Disagreement

Participants express differing views on the appropriate unit for the calculation and whether N/kg is suitable in this context. The discussion remains unresolved regarding the correct interpretation and application of the units involved.

Contextual Notes

Limitations include potential misunderstandings of unit conversions and the definitions of Newtons, as well as the assumptions made in the calculations regarding gravitational potential energy.

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?
