Content Objectives:
Student will be able to
. State the factors affecting air resistance
. Explain air resistance using a model of pushing aside air molecules
. State the factors affecting contact friction and compare to the factors affecting air resistance
. Describe what is meant by the coefficient of friction and explain how it is determined
. Distinguish between static friction and kinetic friction

Show Hewitt video on air resistance (2nd Law)
Go over any questions on air resistance lab.

Do contact friction lab

Hand out CD 5.1 due Thursday of next week for the last time.

Sorry about all the missed blogs.

Handed back and went over Newton's Laws Test

Students did Air Resistance Lab, write-up due Friday.

Ask students what they told their parents about inertia mini-labs or what result they got by measuring their night and morning heights.

Stamped RA 4.1
Went over RA 4.1

Showed how to draw simple free-body diagrams.

Showed free-body diagram for strings and mass. Showed how to graphically solve for the tensions in the strings.
Went over Statics Worksheet - Students did the two problems. Checked to make sure everyone did them correctly.

Quiz next time on inertia
Next time we do the statics lab.

Introduce inertia and Newton's 1st Law
Did you sleep in during the Thanksgiving break? Newton's 1st Law - an object at rest remains at rest
