Handed back Inertia Quiz, Statics Lab
Reviewed some sections of the statics lab that gave students difficulty.

Showed that with two spring balances, the vertical components sum to the weight but you can make the horizontal as great as you please.

Handed out worksheet on graphical solution to statics problems.
Went over example of graphical solution to statics problems. Students did the other four problems on the back of the worksheet.

Handed out worksheet on analytic solution to statics problems.
Went over one example in detail. Students did the other four problems on the back of the worksheet.

Handed out CD 4.2 - due for the last time on Friday.

Reviewed ideas for Statics Lab

Students did Statics Lab and handed it in.

Inertia Quiz

Went over examples of Newton's First Law.

Went over Free-Body Diagram Worksheet.

Thursday, March 19, 2009 - Block 2

Went around the room and asked what the students told their parents about yesterday's class.

Handed back RA 4.1 and went over it. It took a long time.
Newton's First Law - An object at rest will remain at rest and a moving object will continue moving in a straight line with constant speed unless acted on by an outside net force.

Showed the students that a mass of 1 kg weighs 10 N on Earth.

Introduced free-body diagrams - a picture that shows ONLY the forces that act ON an object.

Showed helium balloon on cart demo.
Finished with ballistic cart demo.

Tomorrow we will do the quiz on inertia and the free-body diagram worksheet.

Handed back and went over Projectile Motion Test.

Collected RA 4.1
Talked briefly about inertia.

Students did mini-labs on inertia.

Tuesday, March 17, 2009 - Block 2

Students took the projectile motion test.

When done, they picked up RA 4.1 for homework due tomorrow.

Monday, March 16, 2009 - Block 2

Gave another quiz on projectile motion with rockets. Went over it in class. If students did well, they handed them in for grades. If students did not do well, they could keep them to study.

Answered questions on the problem packet.

Allowed students time in class to work on problems and ask questions individually.

Test tomorrow on Vectors and Projectile Motion.

Thursday, March 12, 2009 - Block 2

Reviewed Rocket Lab results.

Reviewed for test by going over end of chapter questions.

Gave students time to work on problems in class.

Wednesday, March 11, 2009 - Block 2

Gave the general physics quiz on projectile motion followed by the IB Physics quiz on projectile motion. Several students had difficulty. I did not think the students were ready for the test tomorrow so I postponed it until Tuesday of next week.

Answered questions and gave students time to work on problems from the problem sheet.

Tuesday, March 10, 2009 - Block 2

Collected Rocket Lab 2 reports.
Collected RA 3.2

Explained rules of Hit the Bar Lab.

Students did the Hit the Bar Lab.

For those who missed in a competition, they need to supply a data table of all the data for competition 1 and write up the calculations for the competition(s) that they missed.

Monday, March 9, 2009 - Block 2

Wrote program for students to check Rocket Lab 2. Set it up on a laptop.

Lectured on relative velocities. Did a boat problem, rain on the car window, and taking off and landing an airplane.

Handed out RA 3.2, due tomorrow.

Allowed students to either work on RA or check Rocket Lab 2 data.

I will collect the Rocket Labs tomorrow.
