## The physics of Traction Control.

One day when I was driving in the terrible weather of Rochester, I thought, "Hm, why aren't I dead yet? My tires don't slide, even though it is icy." Then it hit me. My car has traction control. Mr. Fullerton wouldn't tell me how it worked, and told me to make a blog post. Traction control is a feature on most newer cars that controls the speed of the tires as they spin. There are sensors in the gas pedal and the wheels that move the car. (ie: front wheels on a FWD car) If the tire senso

## Ice

When I took my drivers test, it was in the middle of the winter, just after a bad storm had hit Rochester. Earlier that day, my dad took me to a parking lot to teach me how to handle myself if I were to lose control. My dad told me to slam on the gas, crank the wheel to one side and learn how to deal with it. As we swung around and around, I thought, "what was the point of this?" Obviously my dad knew I would learn about friction in physics class and that this would be a great blog post. Th

## How you can dodge a bullet

I saw this on myth busters, and I decided, even though they said it was not possible, I can still try, or dream of trying at least. It is possible to dodge the bullet of a sniper rifle. If the sniper rifle were far enough, that is. When the sniper rifle shoots the bullet, 3 components travel towards the target. Light waves, sound waves and a bullet. Light is faster then the bullet and the sound. Having said that, if the sniper was far enough to have a reasonable amount of time between t

## Bowling

Every man wants to bowl well. And let's face it, it's tough. Understanding the physics behind it will help you become a bowling baller. I researched it a bit. Many people know that the lanes are greased, but what most people don't know is that the key to bowling a strike is by hitting between the two front pins, either the 1&2 pins or the 1&3 pins. It is important to know the use of spin and the conservation of energy and momentum when bowling. The lane has little friction, so

## Frisbee

When I play kan-jam, I contently wonder why I cannot stop winning. I realized this is because I am fully in touch with physics when I throw the Frisbee. I did some looking around on the web and learned that spin on the Frisbee gives it stability. The combination of air resistance, lift and gravity causes the disk to glide through the air. The Frisbee connects greatly to Newton's 3rd law. This is because the Frisbee constantly pushes air downward, and in return the Frisbee is propelled upwar

## Ryan's vehicle problems

My dear friend Ryan needed a car. I was gracious enough to give him the beat up ford in my garage. However, physics have worked against this car since 2004. We spent hours trying to get this car to even turn the headlights on. The physics of electrons traveling between my brothers battery and the fords. It took a solid 2 hours in order to get the car to turn over. Finally, my brother got into the car and drove it a bit to get the rust and dust off the car. As a result, the car stall

## Ping Pong

When I was playing Table Tennis at the Rochester Sports Garden, I realized that there is a lot of physics working on the ball. First, the ball hits my paddle, specifically the rubber. Because my rubber is tacky, the ball sticks to it a lot. The friction of the ball on the rubber creates a lot of spin on the ball. The ball usually gets topspin, which also has huge ties to physics, The topspin creates a down force that drives the ball downward into the table. Lastly, the top spin on the bal

## Weight lifting

Because I want to be big and strong like Seth, I decided to go to the weight room today. Obviously I needed to write a blog post on it. In weight lifting, gravity is a huge factor. Without the 9.81 m/s^2 acceleration downward due to gravity, we wouldn't have any weight to lift. Anyone who knows me knows that I'm not a jacked guy, so I start with lighter weights an guess what, gravity was my biggest enemy. Next came some cardio. I ended up realizing that the impacts of my foot hitting th

## My pen fell.

while I was thinking of a blog post idea, I noticed my pen fall off the desk. I immediately knew that I needed to use this because I was wasting time thinking about other ideas. Because of gravity, I needed to pick up my pen, which isn't something I enjoy doing, as It takes too much energy. Obviously, this means that gravity isn't your friend when your lazy. Gravity is also the reason why so many people crack their phone screens. So if your ever mad at anyone or yourself for cracking your p

## Physics due to stupidity

As a child, I have always tried to fly. This never worked and it still hasn't, but just for fun, enjoy my story for now. Last Friday, the last day of me as a 17 year old, I went to work like I normally would. However, this time at work was different. We were raking leaves and such for 3 hours when I had an epiphany. "Let's take these rakes, tie them together with some leaves, and try to fly. So, having said that, we were off to the races. I tied my Boy Scout caliber knot and then

## My boss is loud

Last night at work, I found the difference in amplitude of my boss' voice. Generally, my boss is a fairly quiet guy. He only yells when he has to talk over the noise of lawn mowers and other gas guzzling tools. When he speaks, it is very soft. Therefor, the amplitude of the sound waves is small. Also, he has a low voice, so his voice's frequency is much lower then the female workers in the office. When he yells, however, the amplitude of his voice is off the charts.

## Echoes

Every person, as a kid, always enjoyed echoes. If you say you didn't, then your lying. This past unit, I learned about sound and it's reflection off of objects. The reflection of sound off of an object is known as an echo. As a result of finding this, I know how to find the distance between me and an object based on the knowledge that d=v(t) and sound travels at 331 m/s in air at stp. By measuring the amount of time it takes for the sound to come back, and dividing it by two, I can find th

## My job.

I work at seabreeze over the summer. Amusement parks are literally playgrounds of physics. Rollercoasters rely solely on momentum to keep going, gravity keeps all the carts on the track, and so forth. The ride I want to focus on is the music express. The music express has a plethora of physics. The most obvious is centripetal force. The music express travels in a circle at high speeds. This causes our bodies to fall towards the outside of the cart. In order to stay in, there must be so

## Physics in physics.

In physics class, there is a lot of physics, almost every day. When Mr. Fullerton drinks his coffee, the coffee is being acted upon by an outside force. Gravity helps get the coffee out of his Dunkin' cup and into his mouth. Also, Mr. Fullerton doesn't drink his coffee with any "pollutants." The normal physics of stirring in creamer and sugar doesn't apply to this case. The coffee that Mr. Fullerton relies on to be able to deal with students like me in the morning has a lot to do with physics be

## Sounds

One day I took a splendid stroll through inner city Rochester. I wondered, how come I can hear all the traffic around here? One answer, sound, and here comes another blog post. Sound is caused by the vibrations of atoms. The law of conservation of momentum and energy has a lot to do with this. Because the vibrations travel from atom to atom, there is a conservation of momentum that travels from atom to atom. Also, some times you just can't hear someone because they are too far away, thi
