1. the physics breaking up an old table

when you put a shovel on an old picnic table in your backyard and a leg of the table snaps, it's time for a new table. Problem is, the table can't be thrown away or used for firewood (some parts are just too rotted for anything put the garbage) as it is. It had to be taken apart. The first thing I did was pry off the crossbeams on the table's underside. The crowbar had to be placed at a 90 degree angle and then hammered underneath the crossbeam and pulled. The trick was to make sure the sideways pressure on the crowbar was transferred into the right place. Without something holding the m
2. Bourne again?

In one of my previous posts I examined the physics of The James Bond movie Skyfall. I concluded that Bond's survival was pyisickly impossible due to a fall from a bridge. In this post I will analyze another spy- Jason Bourne- and a certain (spoiler alert) plunge he takes at the end of his third movie. Bourne jumps off a skyscraper and goes into a perfect pencil dive to escape his pursuers. To discover his velocity when he hit the water, I will apply the basic equation v=d/t. The time he fell is approximately 4 seconds, and the distance he fell was approximately 100 meters (The building height
3. the pyisics of alternative energy

I am studying forms of alternative energy for Participation in government class. Since we are studying waves in physics right now, I figured that I would focus on wave energy and how exactly it works. The generators and power cables are placed in the water, usually close to shore. The magnets are placed in a mechanical harmony with the electric wires, like we learned in the last unit with generators. The wave generator works the same way, except instead of fossil fuels the generator uses the mechanical energy generated by the wave. In addition to the up and down motion of a wave, there is c
4. the phyisics of Breaking ( and fixxing) a dishwasher

So my snow day was going perfect untill after lunch. I was doing my dishes and then I heard this metalic clang and the dishwasher door became twice as heavy. I investigated and I saw that the Door is (was) attatched to two springs that slow it down as it nears the floor. One of those had snapped. I should add that I am always extremely carefull with that device and it is 14 years old, so it's not my fault (but I still had to fix it). The phyisics behind the contraption are interesting. Before we did the spring unit I thoght that a springs only purpose was to launch things, as illistrated
5. the phyisics of skyfall: why Bond has accieved "immortal" status

So I watched the latest James Bond movie, Skyfall, for the third time yesterday (thank you netflix) and noticed some irregularites. If you don't want to have the first fifteen muinites of the movie spoiled read no further. So Bond gets shot off the top of a moveing train, falls from an insane hight into a moveing river, and then falls off an equally high water fall. Here's the thing: he survives! I did some phyisics to find out if this was phyisicly possible. The bridge Bond fell off was three hundred and twenty two feet high. From that hight water is like concrete because it's tension w
6. How phyisics changed history part three: the american revolution.

the war of american independence was a revolution in more ways than one. In addition to all the wonderfull things like Individual rights, self reliance, independce, democracy, and freedom, the war for independence broght about an incredible change in the nature of war. The patriots where up against the most heavially armed machine of brute force in the worold, the brittish empire. thier navy and army so far surpassed the rest of the worold, they could hold thier own against an alliance of three european countries. To defeat this mass of oppressive force, the patriots would need corage, ten
7. the phyisics of throwing darts

When a dart is thrown into a dartboard, there are a lot of phyisics involved. For one thing, there is the pricipal that an object at rest will continue in it's speed and direction unless acted on by an outside force. If there where no outside forces acting on the dart, everyone would hit the bullsye every time. But, there is gravity acting on the dart, pushing it to the ground, as well as air resistance slowing it down. Consequently, you have to factor these in when you throw the dart, otherwise you end up hitting the wall. I've found that by aiming a little bit above where I want to hit,
8. why track times are usually slower in indoor track

An indoor track has a few advantages over an outdoor one. For one thing, a person dosen't have to worry about rain and wind that typicly slow a runner down when you run outside. Another advantage is that the air conditions are always the same: 79 deggrees and dry. But the greatest advantage of all is that you have to turn twice as much, because the track is only half as big around. Just kidding, only the first one was an advantage. The fact truth is that RIT could give death valley a run for it's money. The "cottonmouth" ( dry throat) weighs especially heavy on a sick person like me wh
9. the pyisics of juggleing

Juggleing is a great deal harder than it looks. This is because a great deal of phyisics goes into each throw. Each time you throw, you have to calculate in your head the speed of the ball, the force you applied to it and how long it will take gravity to overcome it, and where your hand needs to be at what time. This all needs to be done within fractions of a second. attatched is a vedio of me explaining in greater detail this pricipal as well as trying it out. Will I succued like a profesional clown? or will I fail miserably like a... clown? find out! When I figure out how to publish th
10. Why It's scary to run in the dark

So It gets dark before 5 O'Clock nowadays. I state this not becuase I think you, the reader, are incable of interpreting a clock ( I assume you are because you are literate enogh to read ) but because this fact has some bearing on the phyisics of running. When I foolishly decided put off starting my training run untill four fifteen, I found myself in the middle of the woods forty minuites later with the sun sinking below the horizon and three miles of trails left to navigate. Phyisicly speaking, A couple things happened to me at that point. First, the subconience fear kicks in, the effect
11. how phyisics changed history: part two

Catapults are a subject that we are all framiliar with here. But these devices have had a profound affect on the history of the worold, as well as human understanding of phyisics. They where developed in ancient times, first used on the battlefield by Alexander the great. The mass of the object being thrown had to be aproximated, as well as the size of the launcher, how gravity would affect the missile, and the distance to the target. This acctually led to the development of some of the first math based phyisics, so that Alexander and his commanders could better hit their targets. These d
12. how phyisics changed history: part one

Phyisics has had a tremendous influence on history, in all times and and places. The first instance of goes all the way back to cavemen times. The cavemen origionaly hunted with clubs. There wasen't much phyisics to this, just jump out at an animal and swing. However, as anyone who has ever seen a deer knows, animals tend to bolt at the slightest noise and it is impossible to out sprint four legs. So some anoynomuos Albert Einstien of an 10,000 B.C. created a spear. This way, if he failed at sneaking, he could throw his spear. When throwing, Albert the caveman would have to figure out t
13. The phyisics of a catapult

The catapult project obviously has a lot of phyisics attatched to it. When we tested our catapult, we had some trouble getting it to go forward instead of backward. We where able to fix it by modifying our throwing mechanism to accomodate a ball. What we did not account for, however, was that the baseball we where useing in place of a softball was not the same size or weight as an acctuall softball. Because of this, we could only get the softball to acctually go forward once on test day. what we should have done was make a better throwing mechanism and acctually bought a softball to do a t
14. the phisicks of running

Cross country and track running are like any other sport, in that they both involve a lot of phyisics. When a runner goes out for a training run at 8 miles per hour, they will try to hold that speed for the whole run ( one to two hours.) This means no acceleration after the inital speed is reached. In a race, however, it is different. In, say, a three mile race, if a runner starts with a 5:25 mile, the goal is to accelerate every mile, and get faster as the end of the race gets closer. This seems counterintuitive, because the farther you run, the more tired you get, but that's how you get
15. Intro to physics

I am exited for the catapults and bottle rockets too.
16. first entery

I like to run, hike, camp, swim, bike, shoot and swim, as well as watching t. v. and reading books. I am strong in english and social studies, and I am looking to improve in science and math. This is why i am takeing phyisicks. I also would like to figure out how the worold works, and some of the laws of motion. I home phyisics will improve my math and anyalitical science skills, because I am going to college after high school and will deffinitely need those skills. I am most exited to learn about explosions and to build catapults this year. I am a little anxoius about the regents, partu
