Discussion Overview

The discussion revolves around identifying various forces beyond gravitational and frictional forces. Participants explore both fundamental and non-fundamental forces, including their classifications and characteristics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants mention normal force, tension, spring force, and magnetism as additional forces.
  • Others assert that there are four fundamental forces: Gravity, Weak Nuclear, Strong Nuclear, and Electromagnetic, which account for all observed interactions.
  • A participant suggests that the terminology around "nuclear" should be clarified, noting that weak and strong interactions also involve particles beyond nucleons, such as neutrinos.
  • Another participant introduces additional forces like Van der Waals force and electrostatic force, describing them as offshoots of the main four forces.
  • One participant prompts the original poster to clarify their specific inquiry regarding forces.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the classification of forces, particularly between fundamental and non-fundamental forces. The discussion remains unresolved as participants have differing interpretations and terminologies.

Contextual Notes

There are limitations in the discussion regarding the definitions of forces and the scope of what constitutes fundamental versus non-fundamental forces. Some participants also express uncertainty about the relevance of certain forces to the original question.

i know there are gravitational and friction force.
can anyone tell me names of forces other than those?

Are we talking about fundamental forces here? If so there are only four and they account for all interactions currently observed and are as follows; Gravity, Weak Nuclear, Strong Nuclear and Electromagnetic.

This is true, but for the sake of clarity, there's a slight correction to be made. We seldom attrach the word "nuclear" to both the weak and strong interactions. This is because they don't just have to interact with "nuclear" particles. Neutrinos, for example, are not nucleons, and they only interact via the weak interactions (that's why they could pass through the Earth very easily). The strong force could possibly be mainly for "nucleons", but they are really generally an interaction for hadrons, which also includes mesons in addition to baryons.

Could catch:smile: I'll drop the 'nuclear' in future.
 
I don't know if this counts in the context of the question, but there are also Van der Waals force, electrostatic, torsional, etc.. Those, of course, are offshoots of the main 4.

edit: Never mind torsional, since I suppose that it's just a different way of looking at torque.
 
I think it's time for the OP to step up to the plate and tell us exactly what (s)he is after.
