Variables that affect friction

Today we shared our findings from Lesson 6 and took notes on what variables affect the force of friction.

There will be a quiz Tuesday, October 19, 2010. Topics include forces (elastic, gravitational, friction) and calculating net force. We will review on Monday.

Investigating friction

The class was divided up to investigate if frictional force is affected by: surface type, weight, or surface area.

Tomorrow and Thursday you will work on your lab report. Laptops are available in class to type up your good copy. All lab reports are due by Friday.

Busy Monday

We did a lot today. What a way to start the week. A quick run down of today's events:

• Previous classwork/quiz handed back. Classwork can be corrected and resubmitted for additional credit.
• Homework list for the week passed out (see Class Info)
• Went over net force problems (from Friday)
• Started lab report for Lesson 6 (will conduct on Tuesday)
