As first period began to start Mr. Manning announced to that class that we would be getting new seats today, exciting. While sitting in my new seat I took a quick glance at the mini board, which read the following:
 * 1) New seats
 * 2) 5 min. to turn in lab preformed yesterday
 * 3) DQ
 * 4) Newton's 2nd Law
 * 5) Force units

With Mr. Manning standing in the front of the room, he told the class to put together all of the group members labs and any extra papers (ex. graph) that need to be handed in as well. Once the room, filled with noises of moving chairs and classmates talking with one another, began to get quiet again Mr. manning then told the class to look over the Daily Question(s) and try to answer them as much as possible.

Daily Question(s)
 * 1) Why does Newton's 2nd law state that a net force causes an acceleration? Why not just one force?
 * 2) If the acceleration triples for a constant amount of net force, how did the mass of the object change?

After going over the answers and having our usual little class discussion we were informed that it was nessary to memorize all 3 parts of the law.
 * 1) Unbalanced force acts on a particle, the particle accelerates
 * 2) Product of the mass and the acceleration of the particle equil the unbalanced force
 * 3) Net force is equal to the mass of that particle times the acceleration of that particle.

We were then told to get out page 7 (in the packet) and work on the first page. In the process Mr. Manning blurted that we were going to have a lab tomorrow, "I still need to change it." After being showed how to go about these problems we then went over them also. Then, as if this was not enough, half of page 8 was assigned to be read. In this reading we learned more about sigma F, which means "the sum of the forces" or commonly referred to as "net force/ unbalanced force". We then learned the two types of problems that can be used for sigma F.
 * 1) (sign)F= ma
 * 2) (sign)F= F1 +F2 +F3.....
