Areas that went well for me were momentum and impulse and conservation of linear momentum. What helped me to really understand these two topics were first understand the graphs that went along with them. This included Force vs. Time graphs showing the impulse to be the area under it. These graphs gave me a better understanding of what I was solving for when I got to problems.

Center of mass was the topic I had the most difficulty with. However plotting the points on a graph helped me with this as well. The equation Xcm= (m1x1+m2x2).../m1+m2... really helped me understand finding the center of mass of different points. Finding it for other objects such as rods however was still quite challenging.

My major key to success this week was working more with graphs. Once I understood graphs whether it be just plotting point or graphs such as Force vs. Time, they all helped me get a better understanding of the topic I was working on.

**This week I studied chapter 4 which included work, energy and conservative forces, conservation of energy, and power. I found however that I spent the most time learning and working on conservation of energy.**

**Areas that went well for me included work and power. Work was mainly review and it was good to go back and solidify my knowledge on the topic. This was the same for power as I found I didn’t take many notes. Most of it was review and the questions seemed fairly straight forward. **

**The topics that were more challenging was energy and conservative forces and conservation of energy. What I struggled with at first was the ability to start a question. I was struggling to understand how the energy of a system was being affected and putting it into an equation. However, once I practiced that more and more and was able to do it, the rest of the question came very easy. I would then just substitute in the formulas and would continue with the question.**

**My keys to success are very similar to last weeks as I followed my own keys to success and found they worked very well. I paused a lot more during videos to make sure I was keeping up and understanding every that was happening. I also answered the examples on my own first and then would either compare my answer or get help if I was stuck.**

**This week I focused on the first three chapters of Mechanics, the introduction, kinematics and dynamics. I focused more on dynamics as I feel that is the area I needed more work on but both were very helpful. **

**Areas that went well included most of the projectile motion. Describing motion 1 and 2 were also just review as I knew almost everything covered. Circular and relative motion was a little harder but it made more sense the more I sat down with it and compared it to translational motion. It is very similar in how you calculate and derive expressions as well as equations you use such as converting kinematic equations by just replacing certain variables with their angular equivalents.**

**There were a couple of areas that I found to be more challenging. One being Tension as it was always an area that I struggled with. As I went through however I began to pick up tips on this as well that would help me. One being to establish a positive direction right away. The next being to draw free body diagrams of all of the forces affecting the Tension of an object. After I got these things down it seemed to come a little easier. Calculating friction was also something that I found to be challenging. **

**My keys to success would include slowing down when I am watching the educator videos. It helped me to slow down and pause here and there in order to catch up and make sure I understand everything that has been said to far. I used this the most during derivations as it helped me understand each step of it. **
