Today we learned how to use components to find the net force when several forces are acting on an object. No homework - we finished all of the practice problems in class.

Today we talked about the lab that we completed before Thanksgiving. Your lab worksheet and graph is due tomorrow. Then we talked about Newton's 2nd law (F=ma) and began solving problems.
This week we had a special conference schedule. We finished the Newton's 2nd Law Lab. Make sure you graph your data and answer the questions in the lab packet. Have a great Thanksgiving break!!
Today we began a lab to gather data to determine the relationship between force and acceleration. We will finish gathering data and complete the lab next week.
Today half the class was absent due to the poetry slam, so periods 1 and 2 had a study period. Period 6 began a lab on Newton's second law.
Today we practiced drawing free body diagrams. Homework is a packet of FBDs. I will be collecting it tomorrow.
Yesterday we began talking about forces. You then used a bowling ball and mallet to investigate how force affects motion. Today we will have fun rolling the bowling ball through an obstacle course, and then learn how to draw free body diagrams. This material covers pages 87-92 in your book (Chapter 4).
Today you worked on a review assignment to prepare for the test tomorrow. Solutions to the review assignment are in the google drive folder for the chapter. For the test, you may use a cheat sheet that meets the following requirements: it must be handwritten and cover only one side of a sheet of 8.5x11 inch paper. You will be turning in your cheat sheet with your exam.
Today we practiced relative motion problems. You are supposed to try G71, C54, C62 and C63 on your own. The answers to these problems are at the back of the packet, and the fully worked solutions are available here. Tomorrow we will review for the test on Wednesday.
Today we worked on the projectile review problems. Make sure your lab is done for tomorrow (procedure and analysis). Tomorrow I will give you an angle, and you will need to calculate where to place your launcher so that the marble will hit the target.
The solutions to the projectile motion review problems are in the google drive folder for chapter 3. |
