11/30 Zimmerman

We turned in our Newtons Law Test Review. Hewitt Reading questions on friction was assigned for homework. Class activities consisted of working hard on the Newtons Law Test. It was fun. Something crazy that happened today is that there is a new memory deletion for our calculator for todays test. This crazy thing happened because we used matrices. We didnt really learn or cover any new material in class. We just slave over our test. But one thing I learned is that if you need help, you should wake up extra early and get help! Team I ♥ Life was about to protest the test because a team member was missing (Nathan Turner I) but then he pulled through and showed up, so all was good.

Question of the day:

If your tires lock up when you travel at a high rate of speed on an icy road, what kind of friction exists between the tires and the icy road?

Highly Intelligent answer:

Great question ch. Thanks for asking. The answer is that the friction would be called sliding friction. When the tire is rotating, its surface does not slide along the road surface, and friction is static friction. But when your breaks lock up the tires are not rotating thus resulting in sliding friction.

WELCOME BACK!!

I hope everyone had a great break and is ready to jump back into things! Today in class, we did the Inertial Pendulum Lab. In this lab we explored a device called an intertial pendulum. Note: this device is DANGEROUS! Make sure to tape the "hazardous projectiles" (as described by Coats-Haan) in place before letting the pendulum swing. The point was, to see if the weight of an object has an effect on the period of the device. See, the gravittional force of the mass is removed because the two pieces of spring steel on the device move the mass to a point of equilibrium. After completing the lab, we worked with our teams to correct our diagnostic tests. We took these at the beginnning of the unit. These were turned in at the end of the class. For homework, we were assigned a worksheet of force law practive problems. In addition, a lab report for the Inertial Pendulum lab is due next Tuesday. Oh, and don't forget! We have a test coming up on Wednesday. If you didnt pick up the review before break, make sure to do that.

Question of the day: If you were on a space shuttle, what is one way that you could determine the mass of an object?

Answer: If you wanted to determine the mass of an object in space, you could use the inertial pendulum to time how long it takes for the pendulum to make 20 cycles and then compare with previous findings. I think that the pendulum works nearly the same in space.

Today was a fantastic day in Honors Physics.  We started the day with our Toys in Space presentations, in which we compared the behavior of the toys on Earth and in space.  Each group presented, we made predictions, and then we watched a demonstration video.  Johnny was the wonderful person in charge of lights, but sometimes he slacked a little.  After the presentations were finished, we turned in our predictions papers, and Hunter gave us a great story about never giving up that actually didn’t have that meaning at all.  Instead, it just said not to waste your money trying to get a big Scooby-Doo at King’s Island.  Coats-Haan reminded us that the Newton’s Law Test Review was just sitting on the counter if anyone had the urge to work on it over Thanksgiving break.  The key is online, and it is due Wednesday, Nov. 30, the day of the test.  At the very end of class, we were so honored to pass around Coats-Haan’s prized possession- a piece of a space shuttle.  Happy Thanksgiving:)

QOD: Which toy was your favorite? How was its behavior different when it was in orbit than when it was on the Earth's surface?

My favorite toy was obviously the ball and cup because that was our group’s toy, and it made Hunter feel like a Mexican child.  On earth, you were able to get the ball into the cup, and it would stay there.  In orbit, the demonstrator showed that while he was able to get the ball into the cup, it wouldn’t stay there. Instead, the ball hit the cup but then pushed away.
