Download Lab 4.1 – Mechanical Resistance Using the coefficients of friction

Lab 4.1 – Mechanical Resistance
1. Using the coefficients of friction, rank the
sleds from largest to smallest coefficient.
The larger the coefficient of friction, the
______________ friction there is.
2. What impact did adding more normal force
have on the coefficient of friction?
3. If you had to pull skids of material weighing
1000 pounds around in a warehouse, from
which material in this experiment would you
make the skids? Why?
4. Did it take (more, less, the same amount) of
force to start movement as it did to maintain
movement? Why?
5. Identify and list four real life situations
where friction is desirable, and four where
friction is undesireable.
