## Homework Statement

(This was a problem in an examination test of physics)

Problem:

point 1) Make an example of conservative force;

point 2) Write the vectorial expression

point 3) Choose a coordinate system and find the expression of the potential energy in a generic point in the space

## Homework Equations

I know how to do the first two points but i can't understand what he's asking me in the third point, when he asks me about the "generic point in the space".

How should i Proceed? What is he asking me ?

## The Attempt at a Solution

point 1) I made the example of "Costant force"

point 2) U=Fx

point 3) I got no idea what he's asking me. Can you help me please?
