In this project Cassidy and I created a Rube Goldberg machine. A Rube Goldberg Machine is a complex system set up with a series of chain reactions used to do a simple tasks. The objective of our project was to feed a dog. We had the machine do a series of tasks to get a cup with food in it at the end of the machine to dump out the food into a dish. Our rube goldberg machine started with a series of dominoes. When we pushed the first domino it gave it kinetic energy. This domino will hit the next domino and the kinetic energy will transfer to the next domino. The last domino pulled a string from in front of a marble. The marble then rolled down a ramp and then hit a rubber band. The marble hitting the rubber band created potential energy by
stretching the rubber band and also created elastic energy.The marble came off a rubber band and dropped off an edge when it dropped off the edge there was gravitational energy. The ball then well into a bowl and drops through a hole. When it drops the energy goes to gravitational energy. Then the marble hits dominoes which creates kinetic energy. The last domino is on the edge of a book. The domino falls off which is gravitational energy. There is string attached to the domino that fell off the book and the cup. The string pulls the cup and empties the food. Something we thought would work was a roller coaster car and a ramp. The last domino would hit the car and the car pulled the cup and emptied it. This didn’t work because the domino was not heavy enough to push the car down the track. Another thing we had to experiment with was the rubber bands. We had to adjust the tightness of them so that the marble would bounce off correctly. Without over bouncing. We made our machine out of a cardboard ramp with a series of ramps and rubber bands for the marble to run down. We then had some plastic tubing and dominoes. We put these items in a complex series to make a styrofoam cup empty out.
The robotics team from Carl Hayden high school faces many hardships individually and collectively. An obstacle that they faced was money issues, and they were on a tight budget. Oscar also had an obstacle. He couldn’t join the military because he was undocumented. The money issue is stated in paragraph 17, It states the following “Despite the donations, they were still on a tight budget.” This sentence proves that they have money issues, and they raised a total of $800, and it is stated in paragraph 17 as well, “Oscar and his team raised a total of about $800.” As it is stated in the text before, the robotics team at Carl Hayden’s high school doesn’t have as much money donated to them as others teams, so that limited their options for parts, which puts them at a
We ran into Newtons First Law, which claims that an object resists change in motion, as the marble rolled down the floor it didn’t stop until it was acted against by friction. As we moved on, Newtons Second Law came into play when we were creating our lever as we need a ball that would roll down with enough acceleration that it could knock down the objects. Newton’s second law claims, that F=MA. So, we choose a golf ball since it would have more mass than a rubber ball, but it would have less acceleration when the lever was started. This way, it would knock the upcoming objects. Newtons Third Law claims that every action yields an equal and opposite reaction. This is proven in our Rube Goldberg Machine when the small car was rolling down the tracks as the wheels pushes against the track making the track move backwards. The track provides an equal and opposite direction by pushing the wheels forward.
Explanation: The height of the ramp affects the speed and distance the ball rolls because the higher the ramp, the more gravitational potential energy the ball has, which is then transferred to kinetic energy. The length of the ramp affects the gradient, which affects the speed and distance the ball rolls. The surface of the ramp and marble cause friction, which affects the speed and distance the ball rolls. The weight and size of the marble affect the gravitational potential energy and the amount of friction, which affects the speed and distance the ball rolls.
Have you ever wondered how a record player works? Probably not. After all, who still listens to records? Surprisingly enough, turntables are making a come back. With the recent surge of interest in hip hop music, popular attention has been turned towards the turntable, used by DJs to provide beats, loops and scratching for virtually all of today's hip hop groups.
Furthermore, the mechanism of the machine offered a different interpretation of the working condition. At first the machine operated smoothly and flawlessly. It works according to the inventor’s words. Brian Eggert described the operation of the Machine in his review as the following:
At the beginning of our machine, the golf ball has gravitational potential energy. It is not in motion but as soon as we cut the string the first golf ball will start to roll down the ramp. This will convert the gravitational potential energy into mechanical kinetic energy. This transfer of energy made the ball start to move and speed up
Claw machines are ubiquitous as they are notorious; they are always present in carnivals, boardwalks, drugstores, and restaurants and are infamous for sucking the spare change of players and the claw machines of the past were no different. The first claw machines were called diggers which, “existed as early as the 1890s….built to entice people fascinated by the machinery used in constructing the Panama Canal.” (Rossen, “Dime After Dime: A Gripping History of Claw Machines”). They were created by William Bartlett and were, “mass-produced [in] 1926” (Rossen, “Dime After Dime: A Gripping History of Claw Machines”) and he, “grew rich from their ( the carnival owners) repeat business” (Rossen, “Dime After Dime: A Gripping History of Claw Machines”).
In everything that we do, there is some aspect of physics involved in it. Even if we are just standing still on the ground, or leaning up against a wall, there are still numerous forces acting upon us. This paper will tell of the physics involved in throwing a yo-yo.
Inclined planes are yet another simple machine that you use nearly every day. Any time you walk up a slight hill, you are using an inclined plane. Any time you ride your bike or drive your car up a hill on the way to school, you are using an inclined plane. Even when you push your grandma in her wheel chair up the handicap ramp you are using an inclined plane. So to summarize what an inclined plane actually is, it is a flat surface on an angle that is always used to multiply your force. BUT WAIT! You, Mr. Davis, and I both recently learned that that statement ISN'T always true. You concluded while watching the Olympics that snowboarding ramps aren't force multipliers, but speed multipliers. All inclined planes that are force multipliers have a length longer than their height. However, with snowboarding landing ramps, especially during the snowboard cross event, the big jumps have heights longer than the lengths. For IMA in inclined planes, you divide the length by the height, so when this scenario occurs, an IMA of less than one occurs which indicates a speed and displacement multip...
• The Use of Force is about a girl who may have Diphtheria, but refuses to open her mouth to let the doctor look at her throat. After much struggle, emotional and physical, the doctor forces her to open her mouth and it turns out she does indeed have the disease.
“One machine can do the work of fifty ordinary men. No machine can do the work of one extraordinary man” –Elbert Hubbard1. Machines often are used to make life easier for human beings. A simple machine is described as a device used when a fore is being applied to an object. Simple machines include: levers, pulleys, wheel and axle, gears, inclined plane, wedge, and screws. Complex machines are systems of simple machines used together to get work done.
Sam Esmail’s Mr. Robot, the show that won the Golden Globe awards for the Best Drama in a Television series, Best Supporting Actor for Christian Slater, and a Best Lead Actor nomination for Rami Malek, which is televised on USA Network, isn’t the typical mystery. The story follows the young, troubled hacker, Elliot Alderson, as he tries to understand the scheme he’s been so hopelessly wrapped up in, as well as the identity of the man behind it all. The story’s dark undertones are aided by the backdrop of New York City, particularly the seedy underbelly of the city’s streets, and the underlying greed of corporate America. Each episode introduces a new piece to the puzzle that Elliot’s life has become, and each episode leaves the audience with
The theory of perpetual motion and energy is a topic that is one that is almost an outcast by the scientific community. That is why it so interesting in my opinion. One day I was brain storming and this method just popped into my head. My hypothesis states that a bigger pulley on the router of an electric motor and a smaller pulley on the router of an alternator connected to a battery would put out higher amounts of energy than the same or even smaller pulley on the alternator. The interesting thing about this experiment is that the results actually matched my hypothesis. As far as getting this to run in a continuous fashion if you add an inverter and another battery to this system, the amperage would be enough to power the motor and the electromagnetic field in the alternator. Due to a shortage of funding this inverter could not be brought fourth into this project. With a 4000 watt inverter in theory the machine should spinning continually until something breaks.
Did you know the amount of energy Americans use doubles every twenty years? What is energy? “Energy is the ability to do work, or the ability to move, or elicit change in matter.” (Castro 2014) Energy is just there, it cannot be created or destroyed. It can also be transferred between two objects by using force. We measure energy in joules. It can be converted from one form to another. Energy is transferred with kinetic and potential energy. We use kinetic and potential energy
Energy is used as part of everyday lives and can be used in one form
