11-6

Today in Physics class we walked in, only to find that our seats had been moved. After we finally settled down and got in our new seats, Mr. Manning gave us 5 minutes to get our labs together with our group members. Every group turned in a stapled packet of papers. Each group member needed to hand in their Force and Motion Lab and the group needed to turn in the graph you printed out, and the Recorder's Report. After those were all handed in, we discussed the Daily Question. There were two questions today:

1. Why does Newton's 2nd Law state that a __net__ force causes an acceleration? Why not just one force?


 * Answer to question 1**: Because there's friction. If you want it to accelerate, you must add a greater force in order for it to accelerate.

2. If the acceleration triples for a constant amount of net force, how did the mass of the object chance?


 * Answer to question 2**: The mass goes down by 3 times the amount.

After the daily question, we just went over page 6b, which we picked up yesterday. It talked about Newton's 2nd Law (Law of Acceleration). Then we worked on the Newton's 2nd Law Applications (page 7), which we picked up today at the start of class. We worked with our new partners on numbers 1-4 (the first page). We only had time to go over numbers 1-3 before the bell rang. The answers to those questions are: 1. d 2. b 3. c

That is all we did in class today.
