The Physics of Driving
Physics is involved in our everyday lives, whether we like it or not. One of the things that we do on a daily basis is drive- there's lots of physics in driving! Ever think about why the gas/break petals push back up after you step on them? That's because when you push on the breaks, the break petal pushes back onto you. To get more in depth, Newton's 3rd law applies to driving because when you drive, the action force is pushing against the road and the reaction of the road is pushing against the tires. Also when a car hits a person (let's hope this doesn't happen), the person hits the car. To sum this all up, when you put energy and force into an object, energy and force comes back to you.

The Physics of Wagon Pulling
The blog "amandarocks27" on 3/8/14 posted about how her baby niece has plenty of toys that she will be able to cart around in a wagon once she's older. "amandarocks27" explained how she would figure out the amount of work her niece would have to exert on the wagon to make it move.
The post shows how physics can be used in real life!

Basics of Physics
When I heard the word "physics" for the first time, I had no clue what it was. I didn't know if it was just another type of science that I would be bored with. But, I slowly learned that physics is everything in the universe. You can literally figure out why things do what they do. From throwing a football all they way to electricity, physics covers it all. Physics is truely life. It practically explains the universe.

Workplace Physics
This is a story about my work and physics.
I am not telling you where I work, but I just know I am a busser, and I am very good at it. So a few of the people I work with know I love science and math and physics. One of them actually majored in science so we discuss it a lot. I'll call them S. So S was carrying a tray at just the right position where it was almost straight up and down. (Perpendicular to the floor) Someone asked how the heck he can do that and I answered saying that it was static friction and that since the forces on the plate were just so, the plate would not move unless he tilted his hand more. Which he did and it fell and everyone told me I was smart.
More will probably come because I work with some really cool people who like to talk about physics with me.

Are Cars Speeding on Cooper Road?
Ray, Ben, Julia, Madison, Damian
For our speeding lab, we had to determine if the cars driving north on Cooper Road were speeding or not. We were given a measuring tape and a stopwatch and were left to figure the rest out on our own. We had to describe the kind of car and have at least two sets of data for each car.
First we figured out that there are 15.6 m/s in 35 miles per hour so that we would have a baseline for our calculations. To determine a cars speed on Cooper Road, we extended the measuring tape 15.6 meters and timed how long it took for the car’s front wheels to go from the start of the measuring tape to the end of the measuring tape. We recorded the data for ten cars and wrote a brief description of each car so that we could compare our results with Mr. Fullerton’s radar gun.
After recording the speeds of the cars on Cooper Road we went to are data and compared it to what was recorded with the radar gun. Overall are data was not that off what the radar gun recorded however what data that was off was usually lower then what the radar gun got. In reflecting on this lab we could have had more people timing the cars which would have resulted in more accurate averages. With the timing there could have been someone standing at the beginning of the measuring tape saying “GO” so that the timing would begin at the same time and “stop” once the car got to the end of the measuring tape. Another way we could improve this lab would be through having Mr. Fullerton at the same spot as us recording the cars speed because some cars continue to accelerate as they continue. A final problem we had was that are timing system was very close to the traffic light so not all the cars we recorded were at full speed by the time they reached us.
Are results concluded that there is not a speeding problem on Cooper Road. Our data showed that the average speed between 10 cars going north on Cooper Road was 34.902 km/hr which is below the speed limit of 56.3 km/hr. which is equivalent to 35 mph. We had no one over the speed limit or even very close to it which was a positive conclusion from the data. So no we concluded that there is not a speeding problem on Cooper Rd. if there is anything there is a problem of cars going too slow.

Current Electricity and VIRP Tables
In honors physics, we are working on the current electricity chapter and have started VIRP tables. At first the tables seemed complicated and confusing, but after much practice they have become fun math puzzles.
This link was very helpful to understanding VIRP tables. It was clear and straightforward:

biking in the rain
A couple of days prior to this post I was at a friends house which I had rode to on my bike, however during the time that I was at my friends place it had started to rain. During my ride home I reached a fairly tall and steep, due to the slicked rode I sped up and was unable to control it very well. I was able to control it enough to not land head first on the concrete however I did land head first into a bush. Soon after that we had a lesson and corresponding video on friction which helped show as to why I wiped out hilariously. Because of the water the friction between the bike tires and the ground decreased leading to a much more slick situation. maybe next time I will just call for a ride

Deciding what Angle to use....HELP PLEASE !!
The question is this:
A hiker sets out on a trek heading (N35degreesE) at a place of 5.0 km/h for 48.0 mins. He then heads west at 4.5 km/h for 40.0 min. Finally, he heads (N30degreesW) for 6.0 km, until he reaches a campground 1.5 hours later.
A) Find his total displacement using vector components.
SO, i used Ax = 4.0 cos 35degrees = 3.27
Ay = 4.0 sin 35degrees = 2.29
Then I looked at the answers and it said I should have used the angle 55 degree angle instead of the 35. How do I figure out when to use which angle?

First Blog
(I do not own this video and give full rights to the creator)
As this is my first blog post, and I have no idea what to write about, I choose something that I quite enjoyed doing. When charged with the task of building a Rube Goldberg Machine, I was more than slightly overwhelmed. Thank heavens for my best friend partnered with me, and together we made an amazing design. Quickly we realized that we would have to do most of the planning on the fly as what we planned didn't seem to be going that well. To get ideas, we watched countless videos and tried hundreds of times to get every exchange in our machine to work perfectly. This is probably the best video we watched as it had a fun and contemporary applicaiton. Thus far, this is the most fun thing we have done in my physics class and probaly one of the most informational as people learn best through experience and exploration; for my lab partner and I, we learned through much trial and error.

The Adventures of Cranston
Short Biography
Cranston was born with glasses on his face. These glasses grow simultaneously with him. He is a Nobel Prize recipient for Physics and is actually Newton's great great great great grandson. The resemblance is uncanny. He is pleased to present the first episode of his multi-faceted series.
Newton's First law: An object at rest will stay at rest unless acted upon by an outside force. (Stay tuned for outside force...)
Static Equillibrium: The forces acting upon Cranston (Normal force and the force of gravity) are equal. Therefore, he remains motionless.

Introducing Bob enright
I am a senior at irondeqoit, i play lacrosse and plan on going on to college next year. I am taking regent’s physics to further my knowledge of science and also because i thought that it was an interesting topic. I would like to come out of the class with a greater knowledge of science as a whole. I am not very nervous about the class except for the new material that i have to memorize. I plan on staying on top of the work load, staying focused in class and working with my classmates.

Physics in falling
So, the other day I was walking down my driveway after it had just rained. I was in a rush to get to school because I have physics everyday, which I just love so much. While on the way to my car I slipped and fell. I fell due to the low amount of friction my shoes against the slippery driveway had, or in this case didn't have. The smoother something is, the less friction it has. This is called the nature of the surface. Kinetic friction is what friction while sliding is called and static friction is not sliding.

things I have learned in physics
I have learned many things in physics. In the first few weeks of the class, I felt very confused. As the class went on, I learned that physics is a necessity in life. I've learned things like we never actually touch anything, we just feel it. Also, I know how to find the angle at which a football is thrown into the air. We use physics in our everyday life and need it to understand how everything in the world works. Also one of the things I found most interesting is when we learned about falling cats. Cats can twist their spine while they are falling so that they always land feet first.

Schools Grants & College Scholarships
Finding out ways and means of how you can pursue your higher education with the high costs can be a cause of concern for both parents and students. But with proper research of the variousSchool Grants schemes for financial aid or college grants will give you a solution especially because some of these aids include federal school grants where the students don’t have to pay the aid after graduation and it can be utilized to cover ant expenses while attending college. Federal grants is decided on the financial need of the student taking into account the amount that the family can offer in the section of the Free Application for Federal Student Aid (FAFSA) report; so the student has to be perfectly honest when he fill up the FAFSA application form so that we will be eligible of receiving the federal grants. Once you have been awarded the grant, it is usually deposited in your student account, deposited into your bank or paid by check. The Pell Grant and the Federal Supplement Educational Opportunity Grant (FSEOG) are the two types of Federal Student Grants.
In many colleges they may have funds set apart as student college grants beside the two Federal Student Grants mentioned above. The details of these college grants will be available in the school’s financial aid office which has to be followed up and taken advantage of as early as possible since most of these grants are very limited and gets distributed quickly. Filling up the application for the FAFSA is the first step that needs to be done to avail Federal Student Aid of any kind and over and above this; most schools have their own forms which will have to be filled provided that you qualify for any of the local or private financial aid that is available. Be sure that you know about your family’s financial resources as this information is of prime importance when it comes to deciding your real requirement for financial aid to avail such student grants. All student grants are reserved for students whose families deserve financial aid, it is worth mentioning that if you deserve such grants, it is worth looking into all avenues including student loans and work study

Since I started taking Honors Physics this term, I realized everything we do, involves physics. This seems like an easy enough concept to memorize, but it can be wierd to think about. Bailliexx13, in his/her blog "Physics in studying midterms" on 1/26/14, made me realize that physics is involved when you are even studying. He/she talks about how moving your papers around involve physics. Just think, you are apply physics as you study it! I don't see where we would be without physics. I can't imagine anything, any task, that does not involve physics. In a way, physics controls our lives.

In response to cat density
Shabba Ranks shed light on an area enduring very high cat density. As said in their post, cat density's characteristics resemble that of mass density (how much mass there is spread throughout an amount of space) and charge density (how much charge is spread throughout an amount of space), but it deals with cats. Doesn't it seem like cat videos and physics go hand in hand?
Here is a link to the video:
P.S. I take it that "cat enthusist" is the politically correct term for "crazy cat lady"

Physics Everywhere
A few years ago, it was fall and my dad was making my neighbor clean the leaves out of our gutters. My neighbor had to climb a distance of 30 feet to get on top of the roof. While he was up there, he accidentally slipped. He fell with a constant acceleration of 9.81 m/s ^2 due to gravity. And his speed was .5 meters per second for the whole two seconds it took him to reach the ground. He was very upset after he fell, but he was alright.

Why am I in AP-C Physics?
Recently I've been thinking: Do i really want to take C in high school? So far i feel completely overwhelmed but have been waiting for that "ah-HA!" moment that seems to be drifting away. I think of the students that are taking ap econ, calc BC and physics C, and they seem to be doing just fine, so why can't i seem to handle ap econ, calc AB and physics C? I would feel quite frankly, like a lame quitter if i dropped out, and even the term "dropping out" has, "you fail" written all over it to me. But at the same time I'm afraid that i've overloaded myself and all my grades will suffer from it especially when the material gets more difficult. And the reason i'm doubting my choice to take C is that out of all my AP's, im most confused in this one. Also I researched and most the colleges i'm applying to wont take 2 ap physics credits. Also the curriculum of the degree i want (5 year professional degree in architecture) in the schools i have in mind wont even let me take physics 101 until my sophomore year (Syracuse), or don't require me to take it at all (Cornell). Which i thought was strange but all electives say "free in department elective" or "free out of department elective." But if i do have to take it again in college, are the benefits of taking it now worth all the stress this year? Additionally, if i end up using it as an actual architect which i assume i will, I would rather take it closer to when i'll actually use it so i remember the material. In short, I really don't want to be taking this course *at this time.* Don't get me wrong, i'm interested in the concepts and material, I just don't know if i can handle it right now with my other aps, the truck load of college stuff we have to take care of, and general hygiene.
sincerely
Stressed Out / Worried :banghead)

Based on the philosophy of Henri Bergson and the contemporary developments of Quantum Physics, I sought to demonstrate how these developments are incompatible with a positivist vision of reality, which is still influential in the scientific community. Specifically, in the field of Psychoanalysis, I have shown how this outdated epistemology has been responsible for a manic denial of the theories of Carl Gustav Jung and Wilfred Bion (later stage) as part of an immobilising allegiance to a schizo-paranoid functional tradition imposed by its founder. Finally, I have proposed that supported by the formulations of these renegade analysts, psychoanalysis can progress to a depressive position, eventually transmitting this integrated perspective of reality to the rest of the scientific community and postmodern society in general.
“Omniscience [on the principle of tout savoir tout condamner] substitutes for the discrimination between true and false a dictatorial affirmation that one thing is morally right and the other wrong. The assumption of omniscience that denies reality ensures that the morality thus engendered is a function of psychosis.”
