Discussion Overview

The discussion revolves around several physics formulas related to kinetic energy, potential energy, gravitational force, and electrostatic force. Participants explore the relationships between these formulas and seek clarification on how to prove them, while also addressing the lack of specificity in the original question.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant lists several formulas: kinetic energy (kE), potential energy (pE), Newton's law of gravity, and Coulomb's law, and asks for proof of these formulas.
  • Another participant questions the clarity of the original request, suggesting that there is no single formula to prove as multiple different equations are presented.
  • A participant expresses uncertainty about the relationships between the listed formulas and suggests that they may need to study the question further.
  • There is a mention of Newton's second law (F=ma) and its connection to gravitational force, as well as a reference to Coulomb's law being proven by Coulomb himself.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the original question, with some expressing confusion about the request for proof and others noting the need for clarity regarding the formulas presented.

Contextual Notes

The discussion highlights a lack of specificity in the original question, as well as potential misunderstandings regarding the relationships between the various formulas listed.

kE=gzE=mv²/2, pE=mgh, F=GM m/r² and F=kqı, q2/d²

Anyone knows or familiar about this formula?
Do you know how to proof this formula??

Thank you^^

p/s: For not to make anyone confuse, this is not my homework :)
 
Physics news on Phys.org
Looks like you have several formulas listed: Kinetic energy (what's gzE?), potential energy, Newton's law of gravity, and Coulomb's law. Do you have a specific question about any of those?
 
No , there is no specific questions. What you just need is to proof this formula.

Original Q:
kE=gzE=mv²/2, pE=mgh, General Gravitiy??(is there any of this?) F=GM m/r² and F=kqı, q2/d²
Proof this formula. (@@)

In my opinions,
kE=gzE=mv²/2, pE=mgh, ( proof that these equations is equals to each other) by using this F=GM m/r² and F=kqı, q2/d² (i guess) I am not sure@@
 
you are true
but i think Newton's lawF=ma and F=Gm_1m_2/R^2 => that formula
formula F=Kq^2/R^2 was proofed by Coulomb by assay

But as the Doc says, you have written down several, different equations: it is not one formula that can be proven.

hmmmmmm.. i will try to study back the question again. And see if they really listed which is which^^.

But, if you all can give some more clues, it will help a lot.

Thank you again.
