1. A formula that could be used to measure the force of friction is Ff < mFN.
- If you were given a force measuring device (e.g., spring scale, force probe) and an object, describe in a few sentences the procedure that one could use to determine the coefficient of static friction.
- If you were given a force measuring device (e.g., spring scale, force probe) and an object, describe in a few sentences the procedure that one could use to determine the coefficient of kinetic friction.
2. Refer to this diagram (below) and answer the parts.
Make a force diagram for both masses and make two force diagrams (one for each mass).
From each chart, you will get an equation that involves T.
One will be : T - mg = -ma
By setting the two equations equal to each other you will
find:
T = Ma + Ff = mg – ma
- Rearrange the equation to get the force of kinetic friction
exerted on mass 
mathematically on one side of
the equation. - Since Ff = uFN and FN = Mg,
rearrange the equation to show that the coefficient of kinetic
friction is given by the expression:

Many physical properties, such as force and mass, cannot be measured directly. Rather, some other physical property is measured and the desired physical property is computed from the results. For example, a bathroom scale does not actually measure mass or "weight," but rather the compression distance of a spring. The numerical values on the scale are calibrated from the compression distance using basic physics principles such as Newton's second law. Coefficients of friction cannot be measured directly. In this problem,...
