We are supposed to build a coaster on a website,draw it ,and then give a presentation. There are four roles in this project. The first role is the historian. They find out the history of roller coasters. Next there is the design engineer. They find out what materials are used and how the materials changed. Then there is the physist. They figure out how roller coasters are tested and the height of hills verses loops. Finally, there is the lawyer which is the part I did. I had to find out the laws and regulations for parks and rides. The outcome of the project was pretty good but it took some time to get the coaster right. This is my rolller coaster that failed because I had to much energy. This is my roller coaster that succeded because it had the amount of speed to make it up the hill and stop when it was supposed to.Finally, my group's roller coaster which is called the Scream X.  If you would like to try out the coaster creator click  HERE.

The three laws of motion are: 1.An object at rest will stay at rest unless it is acted on  by an unbalanced force. An object in motion stays in motion with the same speed and direction unless it is actedon by an unbalanced force. This law is often called the law of inertia. 2.Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object). 3.For every action there is an equal and opposite re-action. There were four jobs. The lawyer, the design engineer, the physicist, and the historian. I was the historian. I had to find out the history of rollercoasters. I also had to find out the fastest, longest, tallest, and the biggest. Ryan was the physicist. Natasha was the design engineer. Drew was the lawyer. The outcome of this project was to know the history, the laws, the physics, and the design of rollercoasters. The reason my first roller coaster failed is because it had to much speed and so it crashed. Here is a picture of the coaster that failed. We called our coaster "The Abominable Taco".   The reason my second roller coaster was a success was because it had the right amount of speed. Here is a picture of the coaster that was a success.      Coaster Creator Article posted April 24, 2012 at 03:32 PM GMT • comment • Reads 214

After we learned about Newton's Laws of Motion we started the roller coaster project. These are the Laws of Motion: 1st Law - An object at rest stays at rest unless  acted on by an outside force. An object in motion stays in motion in a straight line unless acted on by an outside force. This law is also known as the Law of Interia.     2nd Law-  Acceleration of an object depends on mass of the object. The size of net force increases and acceleration increases.  3rd Law- When a force is applied to an object the object experts an equal force in the opposite direction.                   The project we had as a group was four roles. The four roles were historian, physist, design engineer, and the lawyer. The historian found out about the history of roller coasters. The physist looked up the physics that were in making a roller coaster. The design engineer looked up the materials and things to make a roller coaster. The lawyer looked up the safety rules and the things that you need in a park to make it safe. I was the historian and I found out the rollercoaster that were the biggest, fastest, and tallest. After our group was finished we went on a coaster creator and we designed roller coasters. Some of them failed but one of ours worked. The ones that failed and to much energy and momentum so it crashed. I did my own coasters one failed because it had to much speed so it did stop then I had one success.Our roller coaster was called Pretzel Twist. This is the failed one.   This is one our group did that succeded. Article posted April 24, 2012 at 03:31 PM GMT • comment • Reads 171

Newton's 3 law's in order are a object at rest stays at rest and a object at motion stays in motion unless stopped by an outside force. For example a soccer ball rolls until the friction of the grass makes it stop. The second law is an objects acceluration depends on the mass, size, and netforce of the object. For example a truck will go faster if it's mass is light. Newtom's third law says when a force of an object is applied a equal force is applied in the opposit direction. An example is when you hit a baseball with a bat. Force is very important in Newton's Laws. In my group we had 4 jobs. Ap had the job of the phisist, AA had the lawyer, KS had design engenieer, and I had Histroian. The phisist job is to work out the phisicks, the lawyer's job is to find out coaster laws, the design engenieer job is to figure out the design of the coaster, and my job was to find the history of coasters. I found out that the first coasters were on mountains and were made of wood.                                                                                         This coaster failed because it did not have enough speed.                                                                       This coaster worked because it had enough speed for the loops but was able to slow down before crashing. Our teams name for this coaster was Shark Attack. This project was very fun if you want to make a coaster cleck here. Article posted April 24, 2012 at 02:14 PM GMT • comment • Reads 231

The three Laws of Newton are: First an object at rest stays at rest unless acted on by an outside force. Also an object in motion stays in motion unless acted on by an outside force which is the law of inertia. The second rule is acceleration of an object depends on the mass of the object and the size of the net force applied. The final law is when an force is applied to an object the object exerts an equal force in the opposite direction.        There were four jobs in this project and here are there roles. The first job was the historian.That job was to find out the history of roller coasters. Like when was the first one made or what is the tallest one right now. The second job was the physicist. That job was to see how Newtons laws play into roller coasters. The third job was the lawyer. That job was to see how safety is involved in roller coasters. The final job and my job was the design engineer. My job was to see how roller coasters are designed. Also to see what they consider before making a roller coaster. For example they consider every inch on the ride and make sure it is safe.  This is roller coaster was a failure because it had to much acceleration.   This roller coaster was a failure because it had to much acceleration and speed. Probably because the first hill was to big. This roller coaster was a success because it had the right amount of speed and acceleration. I adjusted the first hill and thats probably why it worked. Our roller coaster was called Demon Hills. It had all types of devilish features like horns on the loops. It was based really on nothing it was just an idea one of us came up with. Drawing the roller coaster was very fun. Article posted April 17, 2012 at 03:31 PM GMT • comment • Reads 180
 Article posted April 17, 2012 at 03:27 PM GMT • comment • Reads 351 My class just finished the scream machine project for science.  The purpose was to learn how forces act on a sucsessful roller coaster .  We had to study the effects of the forces of friction, inertia, and speed.  The project was very educational. I learned how hard it is to build a sucsessful roller coaster.  Newton's laws play a big part in the making of a roller coaster. The first law of motion says that an object at rest remains at rest and an object in motion tends to stay in motion unless an outside force blocks it. The first law is also called the law of  inertia  (remember that term).  Newton's second law states that if a larger net force is applied an objects acceleration increases. The third law states that when a object hits another object the object hit exerts the same amount of force on the object that hit it.               There were four roles each with a different job. There was a Physisist, Design Enginer, Lawyer, and Historian. I was the Physisist. My job was to study the effect of Newton's Laws on a roller coaster. The purpose was of the Historian was to study the history of roller coasters( where the first one was, how they started etc.).  The Design Enginer had to study how roller coaster designs have changed. The Lawyer  had to study the rules and regulations of the roller coaster.         The outcome of my coasters were one failure and one success. This one is my failure. It failed because it had too much Kinetic energy This one is my success. It worked because it had the perfect amount of kinetic energy and Potential energy. The team's final name for the coaster was Immortality.  The website we used was The National Geographic Jason Project coaster creator.

Roller coasters involves a lot of science like Newton's 3 laws. The first law for example states that an object at rest stays at rest unless acted on by an outside force. This law is sometimes called the Law of Inertia. Inertia is the same as law 1. The second law says that the acceleration of an object depends on the mass of an object and the size of net force applied. If the net force increases the acceleration increases. The third law is that when a force is applied to an object the object exerts an equal force in the opposite direction.   Each group had 4 people the physicist, the lawyer, the design engineer, and the historian. The physicist takes care of the science involved with roller coasters like kinetic energy, potential energy, speed, and velocity. The lawyer gets information about the different lawsuits some parks have. The design engineer find out the layout of the roller coaster and what is needed material wise to make it work. My part was the historian and I had to find out the history of roller coasters and how the design and materials have changed over the years.   We used a caoster creater website to build a roller coasterof our own. In the end my roller coaster succeded the first time I tried but the second time it failed. My first roller coaster worked because the hills were tall enough to give the right amount of energy to get through the hoop and the hoop got the carts over the second hill. My second roller coaster failed because the last hill wasn't  steep enough to stop the roller coaster so it crashed. Article posted April 17, 2012 at 03:25 PM GMT • comment • Reads 229
 Article posted April 17, 2012 at 03:03 PM GMT • comment • Reads 248 In science class we were doing a chapter on the Newton's Laws and did a project to make a roller coaster to understand how much science and math was involved in creating one.  Newton's first law is an object at rest tends to stay at rest unless acted on by an outside force and an object in motion tends to stay in motion unless acted on by an outside force, this law is also called the Law of Inertia.  Which means if a ball is at rest on the ground it will stay at rest unless an outside force, which would be you, moved it.  Newton's second law is acceleration of an object depends on mass of the object and the size of the net force applied.  Which means if you are pulling a wagon with twenty bricks and your friend pulls a wagon with twenty feathers, you (acting as the net force) will go slower than your friend because the mass in your wagon is heavier and you won't be able to pull it fast enough.  The third law is when a force is applied to an object the object exerts an equal force in the opposite direction.  Which means if you have a fan on a skateboard blowing into the sail on the other end they will cancel each other out.  In the project there were four roles for everybody in the group.  There was the design engineer, who found out how roller coasters are designed.  The lawyer, who found out the legal matters in making roller coasters.  The physicist, who found out the science involved in a roller coaster, and the one I was, the historian which found out where the first roller coasters were built and where the tallest and fastest coasters are.  I found out that the first roller coasters were ice slides in St. Petersburg, Russia, and the tallest is Kingda Ka at Six Flags Great Adventure, New Jersey, USA. This roller coaster was a success because it had enough kinetic energy to make it through the loops and hills and it didn't have to much so that it would crash. This roller coaster failed because it didn't have enough speed and velocity to make it over the first loop. We called our coaster the Sharp Pencil because we didn't know what to call it because we saw a pencil and decided to call it 'Pencil' but that was too boring so we called it the sharp pencil.

 Article posted April 17, 2012 at 02:49 PM GMT • comment • Reads 238 I am going to tell you about my roller coaster project and Newton's laws. Newton's first law is also called the law of inertia. It says an object at rest stays at rest unless acted on by a force. The second part of the first law is that an object in motion stays in motion in a straight line unless acted on by an outside force. The second law says that the acceleration of an object depends on the mass of the object, and the size of the net force applied. If the net force increases, the acceleration increases. Finally the third law says that when a force is applied to an object, the object exerts an equal force in the opposite direction. In this project, my group went on a roller coaster online simulater, and measured potential energy and kinetic energy. We worked with velocity, speed, and other things you need to build a roller coaster.  The four roles in the project we had were the lawyer, physisist, design engineer, and historian. I was the physisist. I learned that the three laws of motion, combined with an understanding of motion perception, can explain a roller coaster ridein terms of changing direction, forces, and accelerations. I learned that potential energy means stored energy, and that kinetic energy is the energy of motion. The initial hill, or lift hill is the highest in the whole ride. The potential energy is greatest at the top of the lift hill. The kinetic energy is greatest at the bottom of the lift hill.   While trying out some roller coasters on the simulater, we had ones that failed and succeeded. Here is one that failed.   Now, here's the one that succeeded.  For this roller coaster, my team decided that we should name the roller coaster "Shark Attack" and make the cars sharks.

### The velocity of this coaster affected the way it would stop. If you want to make your own coaster go to google and type in the Jason Project  and you can build your own coaster.

 Article posted April 17, 2012 at 02:43 PM GMT • comment • Reads 1196 The purpose of this project was to use Newton's Laws of Motion to build a roller coaster. His first law states that an object at rest remains at rest and an object in motion remains in motion in a straight unless acted on by an outside force, such as friction and gravitational forces. This law is also called the law of inertia because inertia is the same as his first law. His second law states that the acceleration of an object depends on the mass of the object and the size of the net force applied. As the net force increases so does the acceleration. The third law of Newton states that when a force is applied to an object the object exerts an equal amount of force in the opposite direction. Momentum is the force needed to stop an object. In the project there were four roles- historian, physicist, design engineer, and lawyer. The historian researched the history of roller coasters, the fastest, tallest, etc. The physicist researched the physics in roller coasters. The design engineer found the types of materials the first coasters were made from, what todays coasters are made from, etc. The lawyer found lawsuits regarding roller coasters, laws needed to be followed, and how parks escape lawsuits. I was the lawyer. Some laws I found were that Utah and Arizona rides are allowed to operate without government safety inspections or investigations. I also found out you have to be at least 16 years old to operate a roller coaster in Pennsylvania. After a few tries on the roller coaster simulator, I created a coaster that works. My first coaster had to much speed.             After a few more tries to get the speed down I added a small hill to the end, hoping it would use the extra speed to get up the hill. It did and my coaster was a success. I had just enough speed to make it to the finish, the right number of loops and perfect hill sizes. My team called the roller coaster "The Abominable Taco" because we didn't want to steal a real name. My team member said "The Abominable Snowman" and I was in the mood for a taco so we combined the name to get "The Abominable Taco". Article posted April 17, 2012 at 02:43 PM GMT • comment • Reads 1196
