It is still early in the morning, and I am not yet used to waking up this early because of the long break for thanksgiving. So I walked into room 019, Mr. Manning’s room, and the first thing I did was grab a sheet of paper that was lying on the front table. After taking the paper, I made my way to my seat took out a piece of paper and my pencil, and responded to today’s daily question. There were three today and they went as follows: 1) Identify the action/reaction pair of your weight. Earth pulls on you, you pull on earth.  2) Which is larger? They are equal. 3) How does a helicopter get its lifting force? Blade pushes air downward, air pushes blade upward.  After we went over these answers as a class, Mr. Manning reminded us that we needed a protractor and a ruler by this Wednesday’s class. He also reminded us that we have a test on Wednesday along with our completed reading guide being due. He then told us to please take out the piece of paper that we picked up on the way in to class, and he pointed out that for number four we will be using Newton’s second law. He then set us off to get started on the work sheet. Before we actually got started on the work sheet though, Mr. Manning went over the difference between //balanced forces// and a //Newtonian pair//. Balanced forces have at least three objects being acted upon, and a Newtonian pair only has two. After we went over this and all understood it as a class, we moved on to the work sheet which had to do with Newton’s third law of motion. When we were all finished, Mr. Manning showed us an example of a balloon pushing air out forcing a toy snowman on a sled to shoot forward.
