Find Coefficient of Friction: Force of Friction Homework

Click For Summary
SUMMARY

The discussion focuses on calculating the coefficient of friction (μ) for different surfaces, specifically oil, water, and dry surfaces, using the provided mass of 0.034 kg and acceleration of -0.3644 m/s². The relevant equations include Ff = μ(Fn) and F = m*a, where Ff represents the force of friction and Fn is the normal force. To determine μ, the user must first calculate the force of friction (Ff) using the known mass and acceleration, or reference standard μ values from tables for the respective surfaces.

PREREQUISITES
  • Understanding of Newton's Second Law (F = m*a)
  • Knowledge of frictional force equations (Ff = μ(Fn))
  • Familiarity with calculating normal force (Fn) on flat surfaces
  • Access to coefficient of friction tables for various materials
NEXT STEPS
  • Calculate the normal force (Fn) for the given mass on a flat surface
  • Determine the force of friction (Ff) using the mass and acceleration
  • Research standard coefficient of friction values for oil, water, and dry surfaces
  • Explore experimental methods to measure the coefficient of friction directly
USEFUL FOR

Students in physics or engineering courses, educators teaching mechanics, and anyone interested in understanding frictional forces and their applications in real-world scenarios.

Homework Equations


Ff=mu(Fn)
F=m*a

The Attempt at a Solution


I need help find the coefficient of friction. I'm trying to find the difference of mu between oil, water, and a dry surface, and I lack Ff, or I do not know how to find it without mu. Is there anyway to find the solution. Thank you

Unless you were given varying information for each case, you'd need to look those μ values up in a table

You know the mass and the acceleration.
What/who's law relates Force, mass and acceleration?
