AI Thread Summary
Work is defined as the product of force and distance (W = F*d), with units of Newton-meters (Nm), which is equivalent to joules (J). A joule is specifically the work done by a force of one Newton moving through one meter. Understanding this relationship is fundamental in physics, as it connects the concepts of work and energy. The discussion emphasizes the importance of grasping basic units in physics, as many derived units stem from six primary measurements. This foundational knowledge is crucial for solving physics problems effectively.

Work = F*d = energy transferred?? PLEASE HELP!

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.
PLEASE HUMOUR ME!

Hi ethan5! Welcome to PF! :wink:

A joule is defined as being the work done by a force of one Newton traveling through a distance of one metre. 1 J is defined as 1 Nm.

What is worrying you about that? :smile:
 


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
 

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
