What is the Relationship Between Work and Friction?

Click For Summary
SUMMARY

The discussion focuses on calculating work done against friction, specifically in the context of an inclined plane scenario. The relevant equation provided is WD = F x D, where F represents the force (11,000 N) and D is the distance traveled (6.0 meters), resulting in a work done of 66,000 Joules. Participants clarify the importance of accurately identifying the distance in the calculation and emphasize the need for complete information to avoid confusion.

PREREQUISITES
  • Understanding of basic physics concepts, particularly work and energy.
  • Familiarity with the formula for work done (WD = F x D).
  • Knowledge of force measurement in Newtons (N).
  • Basic comprehension of inclined planes and their impact on force calculations.
NEXT STEPS
  • Research the effects of friction on work calculations in various scenarios.
  • Learn about inclined plane mechanics and how they influence force and distance.
  • Explore advanced work-energy principles in physics.
  • Study practical applications of work calculations in engineering contexts.
USEFUL FOR

Students studying physics, educators teaching mechanics, and anyone interested in understanding the principles of work and friction in real-world applications.

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

Do you consider inclined plane ?

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?
