Investigating friction

Our investigation on forces led us today to think about how the effort force will change due to surface type, weight of the load, and surface area. Groups were assigned one set of variables to test. In class you began writing your lab report for this lesson. Tomorrow, you will conduct the lab and finish the lab report.

All lab reports will be given a test grade and are due no later than FRIDAY, FEBRUARY 5!

Also due Friday ~ HW list for this week.
