In physics this year, I expect to learn a variety of things including how credit card machines read your information when you swipe your card, what properties of light allow us to see, and the causes of the ocean tides. I think studying physics is significant because in general it will help us understand the world around us and unlike most sciences it will help us understand the properties behind everyday occurrences. It’s also important to learn physics because it will help us be more aware of our surroundings. Lastly, physics can open up a wide range of interests that a student might want to look into more specifically. I definitely have a number of questions about physics considering I have never taken physics class but I have a few main questions that I hope will be answered by the end of this course. The first question again involves ocean tides. I live on the beach so I’ve always been curious about the tides but more specifically the size of the waves. I know that waves tend to be bigger when there is a storm or strong wind but what else affects the wave size? Another question I have involves the class itself. Looking at all titles of the units I’m just curious as to how we will be testing these different subjects. For instance, how will we be testing an ice skaters spin?
