Physics Improvement
During these few days, my goal in Physics was to improve in my ability to find knowns, unknowns, use vectors, and find relevant equations in physics problems.
When we first started getting into projectile motion problems, I thought it would be a very hard concept to understand. However, it was just a combination of two other problems that we had learned in the past: free fall and one dimensional motion. I found most of the knowns using the skills that I had learned in the past, like breaking up the resultant vector into x and y parts. However, I had no idea how to find some knowns, like Ax. I also neglected to add a picture to the problem. I learned that Ax is always going to be zero in projectile motion problems because there is no force like gravity exerted in the x direction. I believed it was a good start, but it could have been better.
The next problem I tackled was a bit better than the one I had done before. I only had missed one known, and that was because of the circumstantial problem. In the problem, there was no initial velocity in the y direction; all the force was in the x direction. So, the initial velocity in the y direction was ignored. Nevertheless, I still believe that I had improved from the last time I had done a projectile motion. I had added a picture, and I had more knowns than I had before.
The last problem that is shown was a problem I had done a couple of days after I had done the previous problems. This time, however, I had gotten everything right. No knowns were missing, all my problem solving skills were shown, and I had solved the problem with the correct answer. I believe that even though I knew a lot during the beginning of this unit, I came out of it knowing that I had improved even more and I had mastered the projectile motion problem in only a few days.
