SUMMARY

The relationship between work and energy is defined by the equation Work = Force x Distance (W = F*d), where work is measured in joules (J) and is equivalent to newton-meters (Nm). A joule is specifically the work done by a force of one newton acting over a distance of one meter. Understanding this fundamental principle is crucial for solving physics problems, as all derived units are based on six fundamental units: length (m), mass (kg), time (s), electrical current (A), temperature (K), and amount of matter (mol).

PREREQUISITES
  • Understanding of basic physics concepts, particularly force and distance
  • Familiarity with units of measurement in physics, specifically joules and newton-meters
  • Knowledge of the six fundamental units in physics: length, mass, time, electrical current, temperature, and amount of matter
  • Basic problem-solving skills in physics
NEXT STEPS
  • Research the concept of energy transfer in physics
  • Learn about the six fundamental units and how they relate to derived units
  • Explore practical applications of work and energy in real-world scenarios
  • Study the principles of force and motion in classical mechanics
USEFUL FOR

This discussion is beneficial for students studying physics, educators teaching fundamental physics concepts, and anyone interested in understanding the relationship between work and energy in physical systems.

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
