Quarter 1

So far this has been my funnest class and the one i look froward to the most every day (other than free periods of course). I like this course because of the concepts make sense and when you understand you can understand how and why things act the way they do. My only anxiety is trying to keep up with my classes while trying to apply to colleges and deal with other stresses. Also trying to keep up with everything during the demands of the highschool soccer season. My goal is to the best i can in the class and learn the important concepts that i will use in an engineering major in college. So far i have been putting a good deal of effort into this class. I just have to make sure i do not start slacking off and getting lazy in the future. My performance has been pretty good so far. My tests are good but i gotta do better on my homework and my quizzes could be better to. Overall i'm doing well in this class because i enjoy physics.

Newton's second law

This weekend, me and my brother went running after a workout. Newton's second law states acceleration equals to Net Force divided by mass. Both of us are about equally as strong so our Net Force when running will be about the same but the difference is in our mass. My brother weighs about 30 more pounds than me so he has more mass. Newton's law states that the more mass an object has the more inertia it has. when my brother and I were running 40 yard sprints we were starting at a speed of zero and a net force of zero. At the start, we both had about the same net force when accelerating to our top speed but because my brother had more mass it takes more force to change his momentum because he has more tendency to stay in whatever motion hes in due to inertia. I was quicker to the 40 yard line because i had more acceleration. However, we also ran a mile after and the results were different. I was a little faster at the start because i had faster acceleration but my brother was able to keep up with me easily because the weight difference only affects our acceleration.
