What is the Relationship Between Work and Friction?

Click For Summary

Homework Help Overview

The discussion revolves around the relationship between work and friction, specifically how to calculate work done against friction in various scenarios, including the context of an inclined plane.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the formula for work done (WD = F x D) and question its application in the context of friction. There is mention of using cosine in calculations, which some participants indicate is not part of their syllabus. Others seek clarification on the distance (D) involved in the calculation.

Discussion Status

The conversation is ongoing, with participants seeking to clarify the problem statement and the variables involved. Some have provided numerical values but are still exploring the implications of those values in relation to work done against friction.

Contextual Notes

There are indications of missing information regarding the complete problem statement, which is affecting the clarity of the discussion. Participants are also navigating the constraints of their syllabus regarding the formulas they can use.

Homework Statement
how to calculate work done against friction? I saw alot of people suggesting to use the formula involving cosine if I'm not wrong but it's not in my syallbus, so is there another way to calculate it?
Relevant Equations
WD = F x D

You need to state the whole question or we're just guessing.

As you referred WD=F*D
F=11,000 N
D is a distance meter the tractor goes in 5 seconds.

oh but the answer is (11 000)(6.0) = 66 000 J though

So, what is D?
