Unit Blog Reflection
A. In this unit I learned about the concepts of gravity and momentum. This includes vectors, action/reaction pairs and conservation of momentum. Gravity is the force that everything gives off, and it causes everything to interact with everything else. The formula to determine the strength of gravity is F=Gm1m2/d-squared. Momentum is the force an object has, you calculate momentum with mass times velocity. Vectors are lines that show the direction and magnitude of an object’s projected path. Action/reaction pairs are, well, everything, because everything is affected by everything else and Fa = -Fb . Conservation of momentum states that momentum never disappears, it is just transferred into different objects.
The things that I have found difficult about this unit are all of the particulars for how you answer each problem, especially when it comes to vectors. If you mess up on answering any part, you start losing points. I haven’t overcome these difficulties quite yet, but when I do it will be because of excessive repetition.
My problem solving skills, I feel, are fairly good, apart from the situation I described last paragraph. My effort towards homework could be much better, I will work on that in the future. My effort in activities is around the average, the activities themselves are very interesting, and the mathematics aren’t too complicated. My effort towards blog postings is average as well, given that they are often more fun to do than regular papers. I have been learning, although some stuff I still need to work on, but I do know most of the material.
B Momentum is one of the big things that physics connects to everyday life, whether it’s a car accident or sailing a boat across a moving river, momentum in one form or another governs the behavior of such objects. Gravity is an even more universal concept, as without it the universe as we know it would stop existing.
