Unit 5: Newton's Laws!


We began unit 5 today even though we were missing Mr. Blake :(! Unit 5 was about Newton's 3 laws. The first law stated that any object in motion will stay in motion unless acted upon by an outside unbalanced force. That law also complied with objects at rest. For an example we had to do the "tablecloth trick," in which we used a pen and a paper. We had to remove the paper from below the pen without making the pen tip or fall. It was pretty hard but eventually our group got it! As long as we kept a constant pull and didn't make sudden movements the pen stayed standing up.
            The second law of Newton stated the equation to find force, F=MA, force equals mass times acceleration. We used this when we were doing the practice problems in the packet. We also learned that force and acceleration are directly related and mass and force were inversely related!
            The last law of newton stated that between interacting objects there are equal and opposite reactions. We learned more about this when we did the diagram of the skinny guy and the fatty and how if they collided which way they would be traveling and how fast their acceleration was!
            Today was kind of weird without Mr. Blake but Jon did a pretty good job filling in for Mr. Blake! My picture below is a picture I took a while ago. It reminded me of Newton's first law about how objects at rest will stay at rest unless acted upon by an outside unbalanced force. This paper didn't move while I was taking the picture because it wanted to remain at rest and there was nothing to make this paper move.
