10-24

Objectives: Go over number acceleratin' experiences pages 34-41. We learned how to use the kinematic equations to answers questions. Mr. Manning did number 1 as an example to help our understanding.

On October 24th, we had a shortened period because of the pep rally, but we went over how to solve simple word problems using VT graphs, kinematic equations, and went over a new topic of linear motion diagrams. Linear motion diagrams are a picture of the object that is moving and then use arrows to show the directions of velocity and acceleration. If the object has common speed or positive acceleration they point in the same direction and if the object slows down then they are going opposite directions (there will be an example at the end).

We also talked about accelerometers which is a extra credit opportunity due on Thursday. You must make one by taking a jar and filling it with water and on the cap tape or glue a piece of string that has a cork or other floating device on the end. When you seal the jar be sure that the cork is completely submerged. Now when you hand it in you must answer the question: In what direction does the cork move when you are making a turn? You must answer this question to receive the extra credit.

The homework for the weekend is to do problems 2, 3, and 4 in your packet. Also, there will be a notebook check on Monday so make sure everything is organized (reminder that he has some of the papers so you may be missing certain numbers.. There will also be a test on Thursday on problem solving.

The following is an exmple of a man running with a positive acceleration: Picture may show up as a link, if that is the case if you click on it, it should load in another window.
