Bipro Dhar Physics Homework 14 1. Rotation Solo-Check In Regarding the solo check-in for the rotation unit, especially with angular kinematics and angular momentum, I felt the most confident in my learning compared to kinematics and the dynamics units and conservation. I feel like I was able to understand each question with a sense of being able to solve it through my own understanding of rotation. I was more assured during both the solo check-in and the collaborative assessment because I could substantiate my answers using physics concepts and equations, instead of merely guessing like I did for the kinematics solo check in where I didn’t know any of the concepts and I had to resort to guessing and that let me get most of the questions wrong on the solo check in. For this last check-in I really didn’t need the review sheet and the concepts were easier to understand from the in-class demonstrations Miguel did and from that, I was able to understand the questions through using real world applications. I found the material more comprehensible by reviewing the achieved homework from the pre-lecture videos and taking notes, refreshing my understanding of what we are studying. For the poll questions, I actively participate in discussions with my group (Izzy, Ella, and Hudson), providing my perspective on why a certain answer might be correct, rather than staying silent and letting others decide without thoughtful consideration and actively asking them what could happen if another circumstance or instance might’ve happened. I felt more accepting if I got an answer right or wrong because in reality getting the wrong answer is better than getting the right answer as I can learn from my mistake. Making mistakes can highlight misconceptions or gaps in understanding. When a learner provides an incorrect answer, it signals to both the learner and the educator that there might be a misunderstanding that needs to be addressed. The question I struggled the most with was question regarding the electromagnetism. This was challenging for me because of the amount of formulas that were in the answers. I felt overwhelmed and I didn’t know where to start. Also the diagram was very confusing as there was a rod moving the same direction as the box so regarding angular momentum, would it be conserved or not made it confusing so I was stuck on that problem for some time. The question I felt most approachable was question 14 regarding the merry-go-round as it was similar to the demonstration in class with the ball going around Miguel’s head as you bring the ball in, radius will decrease and thus angular velocity would increase. This the same case as the person moves
closer to the center, the radius will be smaller and the moment of inertia will decrease and as a result, the angular velocity would increase. I believe this check-in has been instrumental in driving me closer to my learning goals, as I previously aspired to make progress in my understanding of physics concepts and I feel like I was able to know more about Conservation of Momentum or Mechanical Energy through learning the concepts and not the equations. Although I had limited knowledge of kinematics, having taken AP Physics a while ago, I feel that I have made significant strides in the Dynamics unit. Then after having more experience and time with dynamics, I felt more confident in the conservation unit. My increased accuracy in the solo check-in and my ability to contribute to the collaborative assessment, explaining the reasoning behind the correct answers using various concepts such as conservation of momentum, has reinforced this belief. Consequently, for the next unit's solo check-in and collaborative assessment, I aim to further improve and advance my grasp of physics. I plan to utilize my knowledge and move beyond relying solely on equations, aiming to elucidate my homework solutions and solo check-in responses using physics principles. I aspire to articulate my understanding of conceptual questions in my own words, incorporating physics terminology. Thus, for the upcoming solo check-in, I intend to enhance my performance by documenting all my thoughts, providing justifications for each answer, and discussing my reasoning to ensure I am on the right track. 2.
