Is Work Equal to Force Times Distance?

In summary, the conversation discusses the relationship between work, force, and energy in physics. The concept of a joule is introduced as the unit of measurement for work, and it is defined as the work done by a force of one Newton traveling through a distance of one meter. The conversation also mentions the six fundamental units in physics and how all other units can be defined from them.

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!

Welcome to PF!

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
 

FAQ: Is Work Equal to Force Times Distance?

What is work?

Work is defined as the application of a force over a distance. It is a measure of the energy transferred when an object is moved by a force.

What is the formula for work?

The formula for work is W = F*d, where W represents work, F represents force, and d represents distance.

How is work related to energy transfer?

Work and energy transfer are closely related because work is the measure of energy transferred when a force moves an object over a distance.

What are the units of work?

The SI unit of work is joule (J). Other common units of work include foot-pound (ft-lb) and calorie (cal).

Can work be negative?

Yes, work can be negative. This happens when the force and displacement are in opposite directions, resulting in a net decrease in energy.
