When someone falls under normal circumstances, they collide with the ground with a certain measure of force and that same force is applied on the person as in Newton's third law. The force applied to a falling person is not instantaneous, but transferred through impulse, it is essentially a change in momentum. So the force of the fall that causes the second highest amount of accidental death in the world is dependent on the impulse or J=FΔT upon impact. The time-span of the impact diminishes the force that would be potentially lethal. Therefore if someone could maneuver a squat out just in time before the impact or hit some deformable substance, the total impulse would be the same but the force is effectively reduced.
A friend of mine expressed her misplaced disgust upon seeing the kinetic energy equation, K = 1/2*m(v^2), on one of the Ap Chem packets. Regardless, the kinetic energy helps define the energy gained or lost in a reaction in the form of heat. If it helps, one can think of heat as the kinetic energy of molecules in random directions. If matter is energetic enough, it may undergo phase changes. This is also a form of internal energy, the work that is performed on the surroundings by a reaction becomes heat and is an example of the conservation of energy.
As people begin to join into larger groups, the very size may become a problem itself. Before the year is too far underway, it is important to note that the size of the group in question in particular causes diffusion of responsibility. Sometimes in groups of three or more, individuals feel less motivation to achieve something or work towards an end, often relying on others to complete a task as they feel the same in turn. Groups also may allow things to occurs as a result of inaction, believing someone else will handle things. Sometimes members will shirk culpability for mistakes, perhaps like a poor grade, and attribute it to the group as a whole. So as the year passes, keep these phenomenon in mind as you may be able to prevent them.
In opposition to social facilitation there is a second case of phenomenon called social loafing. We have all heard, known or experienced of that individual in media or real life group that slacks off, we may be that person. Now this individual is not a wicked sort nor has the capacity to know what exactly could be afoot, like many of us, they act out of circumstance. As study groups form in the physics classroom this may become manifest over time. Social loafing pertains to the perceived decrease in productivity when efforts are combined. A way to think of it is with a game of tug-o-war, a person alone would exert more of an effort than in a group. So next time an activity in presented to your group, keep an eye out for loafing around. Groups depend on each other after-all so keep each other honest workers and stay motivated yourself!
Group work has become especially prevalent in the classroom of '17. As teams form, a psychological phenomenon can be observed under the right conditions, social facilitation. The performance of individuals in the presence of others, in other words as a group, tends to be better on doing simple tasks rather than complex or abstract thinking. In physics C, it is quite often we learn new information and thus the performance of the group with ill-rehearsed tasks and problems will most likely degrade and therefore be ineffective. So as this tend of teamwork endures long into the year, remember that utilizing cooperative efforts to acquire new skills may be ill-fated to end sourly.
So by now most, if not everyone has completed a proper LaTex lab report for a basic measuring circles experience. I cannot know but all the more suspect that people may have had problems with LaTex. I for one had a bit of trouble last-minute getting my PDF printed so maybe I'm awkward with this tool or inexperienced with LaTex. What I could have used before was a helpful bit of information concerning the ins and outs of LaTex which I am certain a few overzealous students are well versed in. Anyways I found an important aid for students that may want to learn more about this newfangled tool since it will be pivotal through out the year. I will include the URL below and wish everyone the best of luck with this new tool.
So on the twenty first of September in the year two thousand seventeen, anno domini we lost many good men to a test. What's important now, moving unwearyingly forward, is to not lose heart. Our forerunners have been through similar sorts so although our path may seem an onerous, impossible kind, a capable hand and mutual counsel will bring us fruition. Keep in mind that retakes are available, studying is worthwhile and AP physics C is a community. In this dreadful hour, we are not merely alone but we have each other's utmost generosity and the whole extent of one another's courtesy.
Some time ago, I wrote a research paper about Isaac Newton for a social studies class. I did not investigate my topic well until after I handed my ill-researched paper in, a poor choice on my part but my curiosity about the subject did not leave me. I began by read a few articles, just enough to have a partial idea of what it was I should have wrote about and the figure I had neglected to properly study. Isaac Newton had a hand in optics, classical physics, and the creation of his laws of motion. He discovered the law of universal gravitation when he was twenty two years old which in total, became a crucial part of forming our modern ideas of physics and natural laws. Eventually he received accolades and held the title of knighthood for his immense contributions. Overall, I think that Isaac Newton should have a bit more attention from the public so his work can come to light.
1.a. Learning is fast, knowledge is composed of isolated facts, being good at a subject is inborn and I'm really good at multitasking.
b. The second belief because many natural occurrences operate on the same dynamic laws and metrics.
c. Metacognition helps us understand the way we think and improve those aspects of cognition.
2.a. The intention to learn, paying close attention to the course material as you study, following as learning style, time spent learning.
b Commitment of information to be considered related and meaningful.
c. Minimizing distractions, developing good metacognition, processing critical concepts and retrieving and applying those concepts.
3 Elaboration: Seeking practical examples.
Distinctiveness: recognize and distinguish concepts, topics and mathematical situations
Personal: information relative to you.
Retrieval and Application: this depends heavily on the correctness and accuracy of the information in question.
Automacity: working independently
Overlearning: do not confuse certain points of critical information.
4.a. 1. metacognition: to prepare our conscience for learning exercises
2.she asked students to gauge how well they performed against how they actually performed
3. Students tend to overestimate themselves and their abilities as well as underperform when the occasion arises.
4. The lack of critical thinking in high schools does not do much good in the way of preparing college students.
5. The mnemonic connections made along the paths of retrieval.
6. Reading, the relations that compose a narrative are analogous to those made by study.
b. They both require proactive strategies to be involved in the learning process. Their relation to concepts prior and mathematics involved as well as following known natural laws must use the strategies described in this video series. Best to keep in mind that answers are obtainable and that deep processing must be achieved simultaneously in study.
c. The choice to be in a group may or may not hinder the efforts of its individuals or as a social organism become an effective team or to isolate one another into focused study a difficult one. However making delegations of members to carry out tasks manages time better than a student alone could.
5.a. Panic and denial.
b.reexamine your study habits, reveiw this exam, speak with your teacher and be more prepared.
C. wholly commit, minimize distractions, attend all classes, set realistic goals and don't slide.
I'm a humble student of IHS, one of many that have elected to enroll in AP physics this year. I like philosophy. I enrolled in AP physics C out of curiousity, hopefully I'm not inundated soon. Throughout the year, I'm eager to gain insights into the natural world and make new friends. It is rumored among the student body that AP Physics C is a difficult undertaking but I have resolve, about half a year's worth.
