Is there always a potential for conservative motion?

Click For Summary
SUMMARY

The discussion centers on the proof that conservative motion is always associated with a potential, which is solely a function of coordinates. It is established that for a motion to be classified as conservative, the rotational forces must equal zero and be independent of time. Furthermore, the condition for a force field to be conservative is defined by the path integral of the force F around a closed path being zero, which is mathematically equivalent to the curl of F being zero.

PREREQUISITES
  • Understanding of conservative motion in classical mechanics
  • Familiarity with vector calculus, specifically curl and path integrals
  • Knowledge of force fields and their properties
  • Basic principles of potential energy functions
NEXT STEPS
  • Study the mathematical definition of conservative forces and their properties

  • Explore the relationship between potential energy and conservative forces
  • Investigate examples of conservative motion in physical systems
USEFUL FOR

Students of physics, particularly those studying classical mechanics, as well as educators and anyone interested in the mathematical foundations of conservative forces and potential energy.

Homework Statement



It is well known that for a conservative motion there is a potential.
This potential is a function of coordinates only.

Prove this.

Homework Equations





The Attempt at a Solution



I think you have to take a definition of conservative motion then for example prove that for such a motion, the rotational forces equals to 0 and they don't depend on time, then it will mean that there is a potential field.


What is the equation for conservative motion?

I guess we suppose that the general form of the force field is F=F(q,p,t)
 


In general, a force is conservative iff the path integral of F around some closed path is equal to 0. This is equivalent to stating that the curl of F = 0.
