In this lab, you will measure the coefficient of kinetic friction \( \mu_k \)
by following a simple procedure using only a weight and a force meter.
You will measure \( \mu_k \) by replicating the same procedure used in
a typical problem about friction

Get some weight that is between 250 grams and 2000 grams (0.25 kg and 2 kg).
Get several force meters capable of of measuring several different forces.

Draw a qualitative freebody diagram of a weight
that is being dragged horizontally along a flat surface.
There are four forces acting on the weight.

Using a forcemeter, find the force of gravity pulling down
on the weight. Remember that when using a forcemeter,
you want to select the meter that is
the most sensitive that is not maxed out,
as outlined in a previous lab.

Using a forcemeter, find the applied force on the weight necessary
to pull it at a constant velocity on the flat surface.
Make sure you are pulling the weight horizontally
and using the best forcemeter for the task.

By using the two forces that you measured and by
using the concepts outlined in the unit on dynamics,
complete a quantitative freebody diagram of your weight
while it is being dragged horizontally at a constant velocity on a
flat surface.

Find the coefficient of kinetic friction \( \mu_k \)
using the formula \( F_{frk} = \mu_k F_N \).

Write a brief paragraph that briefly summarizes the process used to find \( \mu_k \).
Make sure that you refer to the formulas and principles of physics
you used in your analysis.
