## Main Question or Discussion Point

Hi,
How do we relate F*d (Units: Nm.) with energy (Units: joule.). What is the logical link there?
I am trying to get my head around the fundamental principles of Physics because problems always involve so much underlying knowledge more than any other subject I know. If there's some good information on the web I would appreciate your guidance.

Hi ethan5! Welcome to PF! A joule is defined as being the work done by a force of one newton travelling through a distance of one metre. 1 J is defined as 1 Nm.

What is worrying you about that? Hi there,

To add a little to what tiny-tim is saying, in physics, you can solve every problem with six (6) units only, which are the length unit (m), the mass unit (kg), the time unit (s), the electrical current unit (A), the temperature unit (K), the light intensity unit (cd), and the amount of matter (mol).

All the other units are defined from a combination of these six.

Cheers
