Finding the Scalar Potential for a Complex 3D Conservative Force

Click For Summary
SUMMARY

The discussion focuses on finding the scalar potential for a complex 3D conservative force represented by three vector components. The relationship between the force vector \(\vec F\) and the scalar potential \(\phi\) is established through the equation \(\vec F = -\vec \nabla \phi\), where each component of the force is defined as \(F_{x} = -\frac{\partial \phi}{\partial x}\), \(F_{y} = -\frac{\partial \phi}{\partial y}\), and \(F_{z} = -\frac{\partial \phi}{\partial z}\). The discussion emphasizes the necessity of demonstrating an initial attempt at the solution before receiving assistance.

PREREQUISITES
  • Understanding of vector calculus, specifically gradient operations.
  • Familiarity with conservative forces and their properties.
  • Knowledge of scalar potential functions in physics.

I have a conservative force given in three vector components as normal. Each component is a function of x, y and z.

I need to find the scalar potential. I am a bit confused about this because of the force's complexity.

I know the V = (integral) F.dx, for a 1 dimensional problem, but i amn't sure for this one.

So where do I start?

As always, thanks for the great help guys!

First, you have to show your attempt at the solution before help can be given. However, I will say that

\vec F = F_{x}\hat x + F_{y} \hat y + F_{z} \hat z = -\vec \nabla \phi

F_{x}=-\frac{\partial \phi}{\partial x} , F_{y}=-\frac{\partial \phi}{\partial y} ,F_{z}=-\frac{\partial \phi}{\partial z}
