Marking Period 1
This was a test on the test on units, vectors, and forces. So based on all the things we learned in class we had to answer questions based on it. There weren't any requirements. I'm proud of my work because I got a perfect score on a test, and for it to be in physics its like a very proud moment. Especially with this not being one of my strongest classes.
The goal of lab reports is to document your findings and communicate their significance. A lab report demonstrates the writer’s comprehension of the concepts behind the data. Also need to identify how and why problems occurred, explain how they affected your experiment, and show your understanding of the principles the experiment was designed to examine. This assignment was challenging because my group wasn't able to collect enough data to do the lab report then I didn't receive the sample data till days later so this held me back on my work. Then this also is a long lengthy assignment that takes a little minute and I had to cram it into like 2 days.
Marking Period 2
Lab reports are based off labs we do in class. A lab report demonstrates the writer’s comprehension of the concepts behind the data. Also need to identify how and why problems occurred, explain how they affected your experiment, and show your understanding of the principles the experiment was designed to examine. In this lab we reinforced the relationship between normal force, friction, and the coefficient of static friction. The results confirmed that friction increases proportionally with normal force and that static friction is greater than kinetic friction. While measurements on the horizontal plane were more accurate the inclined plane had more inconsistencies maybe due to the surface and measurement errors. Overall despite minor inaccuracies the lab successfully demonstrated key principles of static friction and it's dependent on surface properties and applied forces.
This assignment was a quiz and it kind of called me off guard since it was almost like a pop quiz and I wasn't prepared as I could have been. While I felt confident about most of the questions I do think I got two of them wrong or something like that. if I had studied a little more I think I'd have kind of done much better for sure. This experience showed me the importance of reviewing my work regularly so that I can always know what I'm doing when a pop quiz like this comes up. Next time I'll make sure to prepare more so I can prove my accuracy and confidence.
Marking Period 3
For this lab, I was required to explore and analyze the conservation of linear momentum and kinetic energy in different types of collisions (elastic, inelastic and partially elastic). I had to set things with different masses and velocities while having to collect and calculate the data. Also analyze how momentum and energy changed before and after collisions. The assignment also required data analysis, error discussion, and a reflection on how the theory matched the experiment results. I'm proud of this lab because I successfully applied physics concepts and carefully analyzed data in a detailed and organized way. I showed that I was able to understand the difference between collision types and how momentum/kinetic energy are conserved or lost. All this helped me earn a 96%, showing I was able to meet and exceed the assignment expectations.
The assignment required me to investigate the conservation of energy in a spring mass system and to determine the spring constant or two springs using Hooke's Law. The lab was divided into two main parts. In part 1, we had to add different masses to the springs, measure the resulting displacement, and use the data to plot force v. displacement graphs to calculate the spring constant. In part 2, we explored the conversion between potential and kinetic energy.The assignment also required detailed data collection, error calculation, graphing, and analysis. What made this assignment challenging was the level of precision. Also keeping the spring vertical without having movement. Plus we needed some teacher help which slowed us down. The errors in the data and calculations contributed to my 70%, showing that we needed to improve accuracy, and maybe more detail.
