Have you done anything to try to find this out?

I would suggest you use Google to find the definition of Joule and Potential Energy.

Please note PF guidelines say you need to show some effort before we're allowed to answer.

You can start by doing what I said in my previous post.

Google Joule and Potential Energy. From the definitions of those words you should be able to come up with the definition you require.

Post what you come up with here and I will gladly help you 'refine' it if it's not quite right.

It is against the PF guidelines to just give you the answer to a homework question.

Here is the definition of Joule (http://en.wikipedia.org/wiki/Joule): [Broken]
"It is the energy expended in applying a force of one newton through a distance of one metre (1 newton·metre or N·m)."

Here is the definition of Potential Energy (http://en.wikipedia.org/wiki/Potential_energy): [Broken]
"Potential energy is the energy stored in a body or in a system"

All you did is rearrange the original statement, you need to use the definitions (I recommend reading the wiki pages) to come up with a definition of the original statement.
