NJIT PHYSICS

In this assignment most of the questions were based on finding magnitude and direction. Some questions would ask about acceleration, time, and forces. Most of the questions that revolved on finding magnitude were a bit more easier because we had discussed a bit in class prior to getting the homework. Some of the questions consisted of various parts while others were just one question.  For me, the questions with only 1 answer were much easier to find, only if there were enough given. There were some questions that asked for the mass and weight.  I was still understanding the concept of finding weight and mass. It was a bit confusing for me, which was why I was so confident in my answer. Other questions like asking for force were much easier since I knew that all we needed was the mass and acceleration. Since they were both given it was much easier to answer that questions aside form others. 

This assignment was based on our knowledge of being able to find force and acceleration. Prior to receiving this homework we spent about a class day discussing equations that would allow us to find forces on different systems as well as acceleration. When we started this assignment, it was during a class period. We were each given a question that we would go over as a group. In that group we were able to figure out equations that we would need  for the question we had. In my case, I was tasked with question 5.13 which was asking to find acceleration, force, and time. We first, identified the givens , which would then allow us to think about what equations can be used with the givens and what needs to be found. For the acceleration, we used a kinematics equation. As to find force it was much easier since we were given the values and just needed to be put into the equation. With the question that I was assigned I found it more easier, once I had to start doing it on my own with the other questions I got a bit stuck. I found myself stuck on question 5.15 because it involved finding different forces which I was not so good at.

In this experiment our main goal is to compare and contrast the coefficient of static friction on an inclined plane. To conduct this experiment we would use everyday objects to show its reliability to everyday life. We know that friction is the force that opposes motion. There are two different types of friction, kinetic and static. Kinetic friction is the force that acts when an object is moving. Static friction is what happens between a motionless object and its surface. After the movement of an object, that is when kinetic energy is exerted. Based on what we know of this experiment we will determine how static friction is seen in different objects by angling the object and waiting for their movement. By the end of the experiment we saw how much static friction is applied in everyday objects and its ability to move.  In this lab report, I believe I was able to thoroughly describe what when on in the lab, both the good and bad. I made sure I detailed every procedure we took or changed to get the results we did in this lab. Although I am not sure how well I did with the equations I believe I used it to the best of my ability. In addition I believe the lab report answered and refereed back to all the requirements in this lab.

In this experiment our main goal is to explore the conservation of linear momentum and impulse-momentum theorem.  We know that  linear momentum is defined as if two objects collide, and the final momentum should stay the same. With this experiment we wanted to observe this reaction in fully elastic and inelastic collisions. One important thing to remember is that this experiment was conducted on an online network. In addition it was an individual assignment. If there are any errors it would be because we may have imputed something wrongfully in the virtual system. In this experiment I personally did not experience many errors, so there was very little data on it. All my data was clearly analyzed and also described to the best of my extent. By the end of this experiment we should have been able to see and determine how the conservation of momentum affects these collisions differently and why.  Based on the results I was able to gather I was able to determine that the momentum is conserved in these type of collisions. In addition , it made me wonder what other types of energies are conserved.

Throughout our physics course we consistently incorporate kinematics equations to help us in various problems. It is something that we have mastered in using and knowing. This year we learned that the kinematics equations that we have used are incorporated in linear problems. Now, since we are working with inclined planes, we discovered that there is something known as angular kinematics. This deals with the same equation but different symbols. With all that we know, we were then quizzed on the two sets of kinematics equations. All we had to do was write the correct linear and angular kinematics equations. Since they are similar equations just with different symbols it was easy to remember. I was able to successfully write the correct equations for each set, but I did fail in one thing. I was too focused on trying to write the equations, that I forgot to make sure I incorporated every single aspect of the equation. The number one thing that I forgot to do was make sure the symbols had vectors. There were various ones missing which was why my grade went down. Those vectors are important to the context of the equation.

As part of our new unit, we started off by conducting a lab. The lab consisted of modeling rotational static equilibrium on a system. For this quiz we had to reflect on the given procedures provided by our instructor. We were provided with a procedure sheet and instructions explained to us what the lab is going to be about and things we should look out for. Often it is difficult to understand the procedures given  but eventually I felt like I understand enough of what the lab would be about. So, during the pre-lab quiz I believe I did a great job in putting in my understanding of the lab. The procedure was a big help as it really allowed me to dive into what the lab would be. As a result, it seemed like my ability to understand the content in this lab helped in developing the lab report that was due after the experiment was finalized.

Prior to taking this exam we spent a few days discussing universal gravitation. We took a look at the force of gravity, escape velocity, period, aphelion, and perihelion. We went over equations that would be used to find these variables in class. So, before the quiz we did have some type of understanding of what the concept of universal gravitation was about. Even so, during the exam I was stumped. The only equation that I felt I was integrating properly was the force of the gravity equation.  When it came to finding escape velocity I was confused as there were two different equations that I knew but I was unsure which one would fit the problem. The thing that did help me was putting down all my givens. Even so, I was still struggling in finding the velocity which I needed to incorporate using equations we had gone over before.
