This essay will talk about the Rube Goldberg project that I, Chandler Works have completed. The materials that I have used in this project is a car, dominos, a marble, blocks, and a bell. I used paper towel roles as the ramp so that everything can travel in its path. We also used little pieces of cardboard as a stopper, so the car or marble doesn't keep rolling after it hits the dominoes. At the end of the project, the dominoes are supposed to knock over and hit the bell to make it ring. At the beginning, the car roles down the ramp (Kinetic Energy). Once it hits the stopper, it loses its Kinetic Energy, and turns in Potential Energy. The force of the car hitting the stopper, makes the dominoes fall (Gravitational Potential Energy), which
Let's figure out how much force a typical car might use to push its tires down the road. Let's say our car weighs 4,000 pounds (1814.369 kg), and the tires have a CRF of 0.015. The force is equal to 4,000 x 0.015, which equals 60 pounds (27.215 kg). Now let's figure out how much power that is. If you've read the How Stuff Works article How Force, Torque, Power and Energy Work, you know that power is equal to force times speed. So the amount of power used by the tires depends on how fast the car is going. At 75 mph (120.7 kph), the tires are using 12 horsepower, and at 55 mph (88.513 kph) they use 8.8 horsepower. All of that power is turning into heat. Most of it goes into the tires, but some of it goes into the road (the road actually bends a little when the car drives over it).
In this project, Firstly we have to keep empty the pen drive to perform the process otherwise we might collapse
The ball behaves like a spherical spring. When the ball hits the floor it exerts a force on the floor and the floor exerts a force on the ball. This force compresses the ball. The force that the ground exerts on the ball does work on the ball, since it is in the same direction as the displacement. The gravitational potential energy the ball has before it is dropped is converted into kinetic energy while the ball is falling and then into elastic potential energy as the force from the ground does work on the ball. But because the material the ball is made of is not perfectly elastic, friction converts some of the energy into thermal energy.
Our group’s Rube Goldberg machine, Phone Call Food, completes an easy and difficult way to feed your dog. This machine features small manipulated transformations through energy. Exactly how are people suppose to feed your dog when no ones is not home? The series of energy transformations will eventually feed someone's dog, and the first step is just to call.
There are also many differences in between both these characteristics. One is that kinetic energy is the energy that an object possesses due to its motion. Potential energy is the pull of gravity. Potential energy pulls the skateboard back to earth. Kinetic energy is the skateboard's energy while in motion.
Investigating the Relationship Between the Braking Distance of a Toy Car and the Height of the Ramp
... presentation and added pictures to go with them. This was probably the longest part of the entire project. Then, I put animations in; I tried not to over exaggerate it. I got creative when it was time to put the music in. Society has a tune that is about society, as plain as it gets. With Advancements, came music that sounds futuristic. Which really goes with it. Spiritual was a tough decision. I could not determine between two songs. Comfort definitely had to be George Michael; he comforts everyone. Education is kind of based on a stereotype with the intelligent human beings being able to play piano. I absolutely had to use elevator music for simplicity. It does not get more simple than that! I enjoyed doing this project. I got to be creative but still be logical. Most fun project I have ever done honestly and I hope that future assigned projects are like this.
We want to start an amusement park, titled Fun Land because we consider it to be a fun family experience. A large amount of money can be profited from the experience. Our short term goals include getting the business up and running with reliable employees, getting the Fun Land name out into the public, paying off some of the debt, and giving customers a good experience. Our goals in five years include having new and attractive rides, good flow of customers, and good reputation. In ten years we want to generate millions of dollars, expand, and build new and exciting rides. We want to provide a safe, affordable, and joyful experience for each and every one of our customers. We believe strongly in honesty so our rides would be monthly inspected and all foods will be properly maintained. We will also provide refunds for any mishaps or unsatisfied service. Fun Land is set up as a partnership between Shur’Myra Lillard and David Chan, as partners we will share the responsibilities and risk in starting a new business. Shur’Myra will be the staff manager and David will be the financial manager. Both will be responsible for hiring engineers for the rides and other employees. Shur’Myra Lillard participated in marketing management class, is well organized, and is cooperative. David Chan also participated in marketing management class and honors mathematics class. He is hardworking, and organized.
In step 4, the car slams into the ball with contact force that makes it start rolling. On to step 5, the ball increasingly speeds up from positive acceleration as it goes down the ramp because of the force of gravity. Then, there is step 6. Step 6 starts at the exact moment the ball hits the first domino that is standing there waiting. This is contact force that makes all of the dominoes fall one after the other like a chain reaction. Step 7 happens after that. Step 7 is when the last domino hits the button on the tape measure. The tape measure quickly pulls back the extended measuring tape coming out of it. The measuring tape is tied to straw like objects that create a wall to keep the marbles from falling. The measuring tape flies backwards creating tension force on the measuring tape. In step 8, the marbles all drop because the wall was removed from step 7. The reason the marbles actually drop instead of stay floating there in the air is because of the force of gravity. Step 9 is when the marbles land in the bucket. This is contact force. Step 10 is next. There is a platform under that bucket and under that there is a
...t the total amount of energy never changes. Let’s assume that the cue ball has 10J of PE. As it’s hit, PE is at its highest (10J). When the ball is going down the alley, the sum of the ball’s PE and KE remains constant at successive positions ¼, ½, ¾, and all the way down. (This I also read ahead and found in the book). As soon as the ball has reached its highest point, PE and KE are equal (5J), and on the way down KE increases as PE decreases. When the ball lands, KE is 10J and PE is 0.
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.
“Even though roller coasters propel you through the air, shoot you through tunnels, and zip you down and around many hills and loops, they are quite safe and can prove to be a great way to get scared, feel that sinking feeling in your stomach, and still come out of it wanting to do it all over again (1).” Thanks to the manipulation of gravitational and centripetal forces humans have created one of the most exhilarating attractions. Even though new roller coasters are created continuously in the hope to create breathtaking and terrifying thrills, the fundamental principles of physics remain the same. A roller coaster consists of connected cars that move on tracks due to gravity and momentum. Believe it or not, an engine is not required for most of the ride. The only power source needed is used to get to the top first hill in order to obtain a powerful launch. Physics plays a huge part in the function of roller coasters. Gravity, potential and kinetic energy, centripetal forces, conservation of energy, friction, and acceleration are some of the concepts included.
Abstract: The purpose of this instructional design project was to create and evaluate an interactive PDF module on establishing a hybrid learning course for the Vietnamese teachers of English at the Center for Foreign Affairs and Language Training (CEFALT) in Ho Chi Minh City, Viet Nam. The module provided the teachers with basic concepts about hybrid learning, skills in using Ning (a social network site) for class, effective incorporation of available technologies into a lesson plan, and a framework for establishing a hybrid learning course. This project included a formative evaluation which was conducted on 16 Vietnamese teachers of English at CEFALT. The data collected from the teachers’ work on the module, pre-test, post-test, and surveys indicated they learned a lot from the instructional module and wished for their school to adopt a hybrid learning mode in the near future. The research findings further revealed that the interactive PDF features of the module greatly helped engage and stimulate the teachers in their learning process.
When an attempt is made to push a car from rest on concrete, the coefficient of static friction is so high (almost 1). However, once the car starts to move, it is easier to keep pushing it because the coefficient of kinetic friction is lower (almost 0.8). Similarly, when an attempt is made to push a car from rest on a wet road, the coefficient of static friction is not that high (almost 0.6). However, once the car starts to move, it is easier to keep pushing it because the coefficient of kinetic friction on wet road is lower (almost 0.4). Furthermore, when an attempt is made to push a car from rest on snow, the coefficient of static friction is lower (almost 0.3). However, once the car starts to move, it is easier to keep pushing it because the coefficient of kinetic friction on snow is lower (almost
Verification of Originality: The above-written project is a product of my original thinking. I understand that if proven otherwise, I receive a grade of zero on this test-weighted paper and will sacrifice my honors credential for English class for the school year.
