11/28 Miley

Today was the first day back from break, so nothing was due or turned in. In class we were given two assignments as a group, the inertial pendulum and to retake the diagnostic test. Most groups began with the pendulum lab. The objective of this lab was to remove the gravitational force from a mass and see its effect on the period. We did this by timing the amount of time it took different weights to cycle 20 times. Do to the dangerous nature of this lab, we had to carefully tape the weights and ensure that the pendulum wouldn’t break. Most groups recorded this data down for the lab report that will be due on December 6^th. The next thing we worked on was the diagnostic test. As a group we had to retake the diagnostic test for correctness and to ensure that the members in our group understood the questions. When completed, this was turned in for a grade. Our homework was the Force Law Practice Problems. Mrs. Coats-Haan also reminded us to pick up the Newton’s Law Test Review Guide if you hadn’t already.

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

Similarly to the inertial pendulum lab, we could tape the object to the pendulum and time how long it takes the mass to make 20 cycles. We would repeat this process and take the average time, just as we have done in the lab.
