Semester of Physics

As a long semester of physics comes to an end and finals approach right around the corner, it seems that many of the things we learned in physics are things that we all know already and use it in our everyday lives, but just never really knew. Physics has opened my eyes to how the world works and how we interact with it everyday. From relationships, kinematics, vectors, to force, momentum, and energy, everything we learned is applicable in our everyday lives. Along with that, I think that physics, as a class, has taught me to use my time wisely. With all the blog posts we had to do that were due every Sunday and all the practice assignments that were given to do the week before the due day, physics taught me that without correct and efficient time management not only will your work will be rushed but also you won't understand it. I learned that if I can improve my procrastination I can do a lot better not only in physics but in my other classes also. Physics is like chemistry in that if you don't pay attention from day 1 and remember everything from day 1 then your screwed because everything is applicable in physics because everything is related. With a correct understanding of physics, it can really be fun like during labs and such. So as this semester of physics comes to a set, it will once again rise again next semester offering challenges and fun.

Energy #1

This week we began learning about energy. We learned the different forms of energy which are kinetic, spring, and potential. We also learned about work, which is the exertion of energy. Energy is measured in joules and watts. This is a picture of me and my environmental science class doing the Ka'ena point hike from one side to the other. It was a long and very tiring hike. In the blazing sun we used a lot of energy walking up and down and side to side. We lost energy because of the amount of work our bodies were using. While our bodies were working it was exerting kinetic energy because we were moving the entire time. Potential is when an object is at rest and spring is when an object is pulled back at a certain distance then projects forward. I didn't know that energy was in physics!
