Discussion Overview

The discussion revolves around the formulation of the equation for net force (ForceNet), exploring different expressions and interpretations of the concept. It includes contributions related to basic physics principles and mathematical representations.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant states the equation for ForceNet as Fnet = m x a.
  • Another participant proposes Fnet = EFx(squared) + EFy(squared), defining EFx and EFy as the sums of forces in the x and y directions, respectively.
  • A later reply challenges the previous formulation, suggesting that Fnet also needs to be squared, referencing the Pythagorean theorem.
  • Another participant corrects their earlier post, clarifying that the correct expression should be the square root of EFx(squared) + EFy(squared).

Areas of Agreement / Disagreement

Participants express differing views on the correct formulation of the equation for ForceNet, with no consensus reached on the appropriate expression.

Contextual Notes

There are unresolved aspects regarding the application of the Pythagorean theorem in this context and the correct interpretation of the terms used in the equations.

equation for Fnet

Fnet=EFx(squared)+ EFy(squared)

EFx= the sum of all forces in the x
EFy= the sum of all forces in the y

I'm afraid this is wrong. Fnet too had to be squared. (Pythagoras Theorem)
 
i forgot to put that its the square root of EFx(squares) + EF(squared)
oops :smile:
