Trolley Investigation Choosing a Variable Before I begin the investigation, I must first decide which variable I should investigate. Variables can be divided into 2 major groups: dependant variables and independent variables. In measuring the behaviour of a trolley the dependant variable is speed. This is because the speed will change when other variables are changed. An independent variable is a variable which cannot be affected by other variables. There are many independent variables
Investigation of the Speed of a Trolley Down a Ramp and Its Gradient In this investigation I will be testing how the speed of the trolley is affected by the gradient of the ramp. The speed of the trolley will be affected by the gradient of the ramp by many factors. One of these factors is gravitational potential energy. GPE is the energy stored in an object because of its height. The energy is stored as a result of the gravitational pull of the earth for the object. GPE is also affected
Speed of a Trolley Investigation Investigation into whether the height of a ramp affects the speed of a trolley travelling down it. Aim: In this investigation I will place a trolley at the top of a ramp and then release it. Then I shall try to calculate its speed and from these results I can obtain whether the height of the ramp increases or decreases the speed of the trolley. When the trolley is raised to the top of the ramp, it gains a certain amount of gravitational potential
the Effect of Mass and Speed of a Moving Object on Its Stopping Time The investigation is about the mass and speed of a moving object and how this affects its stopping distance due to the changes in energy needed to brake. Since I cannot measure the speed and energy accurately I shall change the definition of my investigation. The problem/task I will be investigating is how the mass of a moving object – a trolley, affects its stopping distance. [IMAGE] [IMAGE] Stopping Distance
Investigation of Energy Stored in a Spring Aim:- To investigate how the velocity of a trolley when different spring compressions are used. For this piece of coursework I am going to investigate how the velocity of the trolley over a set distance, is proportional to the compression of the spring. I plan to use two different methods of carrying out the investigation. These methods are :- A Light Gate : - The trolley had a piece of card attached to it, on the top.the spring of the trolley
Investigation of the Relationship Between Mass of a Vehicle and Its Stopping Distance Problem The problem to be investigated is "how does the mass of a vehicle affect its stopping distance when brakes are applied?" This problem is related to the conservation of energy and will be investigated through a trolley going down a ramp. A simple trolley will be used to represent the vehicle and weights attached to the rear of the trolley via a pulley system will act as the brakes. Throughout the
Rolling a Car down a Ramp Investigation PLANNING When planning my experiment, I will need to take into consideration the following points: - Fair testing - Equipment - How many results I will take - What range of variables I will experiment with I will be investigating, by varying the height the summit of the ramp is raised off the ground, if the average speed increases or decreases. Method ====== I have decided to produce a step-by-step guide for each experiment
the Speed of a Trolley For this piece of coursework, I intend to investigate the relationship between the heights of a ramp to the change in speed. I will be measuring the speed from these heights: - * 5cm * 10cm * 15cm * 20cm * 25cm. Formula AIM The aim of this investigation is to find out what the relationship his between the height or a ramp and the change in speed. Hypothesis The greater the height of the ramp the more the speed of the trolley would increase
suburbia. In the article "Joyride", Kunstler identifies the reasons for, and attraction of, a grand public relocation to previously uninhabited areas outside main city centres. Kunstler argues that it was, in part, the replacement of the streetcar (or trolley), and later the automobile, from the horse-powered transit of earlier 20th century life, that ignited weekend traffic to expand outside urban centres. "Joyriding" on weekends, as Kunstler explains, made suburban areas more accessible and attractive
indicate that the PFC is also responsible for regulating emotions and decision-making. A study was conducted in which participants were presented with three dilemmas. One dilemma was called the Trolley Dilemma: a trolley is headed toward five people standing on the track. You can switch the trolley to another track killing only one person instead of five. Subjects were asked to decide between right and wrong. Brain scans of the participants show that contemplating the dilemmas activates
Physics Institute of the University of Rome. He was shown the writings of Max Delbruck, who had boldly stated a gene, was a molecule. Salvador later said that Max’s writings were the “Holy Grail of biophysics.” While living in an old broken down trolley car in the streets of Rome Salvador started a conversation with a microbiologist by the name of Geo Rita. Geo introduced him to bacteriophage, Salvador believed he could prove Max’s theory. He fled Europe in 1940 when the Nazi war machine was an approaching
effects the acceleration of a small trolley with a weight of 1kg. Variables: The variables I will keep the same are: - the weight of the trolley - the angle of the surface/slope - length of the surface/slope - the surface of the surface/slope I am going to change the mass acting on the trolley through the pulley. This mass will be measured in grams. I will put on masses from 100g to 800g. I am going to measure the acceleration of the trolley in m/s as the mass on the pulley changes
Conditions • For this particular experiment the gain of the output for the strain gauges are set to 1 as 0 to 8 degrees slip angle is been measured. If smaller angles are measured a larger gain may be required. • The total displacement of the trolley that runs along the track is approximately 2.17 meters. However, this may slightly vary in the results, especially with higher slip angles due to the reaction force acting on the reversible hydraulic motor that drives the track. For consistency the
Acceleration of a Trolley Plan An unbalanced force causes an object to accelerate. The acceleration happens in the same direction as the resultant (or unbalanced) force. The size of this depends on the mass of the object and the size of the force. The force on a small object is bigger than the same force acting on a bigger object. If the mass stays the same but the force gets bigger, the acceleration also increases. The equation to find acceleration is: [IMAGE][IMAGE] when [IMAGE]=
around the city I’ve come up with several ideas. Electric cars would create less pollution than gas cars so those would highly be encouraged. More encouraged than that would be bikes, walking, and a city trolley system. Certain streets would be blocked off from cars, allowing only city trolleys and bikes through. Also, some streets would be narrower and bike paths would be mandatory along any new street tha...
and 30cm wide. 2. Bricks or wooden blocks 3. 2 dynamics, trolleys or toy cars 4. Plasticine 5. metre rule Method: 1. Two plasticine dummies weighing 20g each were made and placed on the trolleys. 2. Trolley B was placed 30-40cm in front of the ramp. 3. Trolley A was placed 100cm from the end of the ramp. Directly in line with the other trolley. 4. Trolley A was released and was let to collide into Trolley B, observations were made on what happened to the dummies. 5. The
The Bystander at the Switch case is a fundamental part of Thomson’s argument in “Trolley Problem.” The basis of her paper is to explain the moral difference between this case, which she deems morally permissible (1398), and the Transplant case, which she deems morally impermissible (1396). In the Bystander at the Switch case, a bystander sees a trolley hurtling towards five workers on the track and has the option of throwing a switch to divert the trolley’s path towards only one worker. Thomson finds
Jake Seiter March 5th, 2014 The Making of a Hardrock Miner The Making of a Hardrock Miner written by Stephen M. Voynick, describes his own personal experiences as a hardrock miner in four different underground mines in the western United States, the Climax molybdenum mine in Colorado, Hecla Lakeshore Project a copper mine in Arizona, and two uranium mines in Wyoming. Rather than a book telling of the fortunes gained and lost, this book was about the relationships gained, but then also lost through
Trolleyology In this week video discussion, the main subject is it ok for the trolley to kill five or one individual that are tied to the trolley track. The back ground of the scenario, remains a person is on a footbridge looking down on the unfolding disaster. However, a fat man, a stranger, is standing next to you: if you push him off the bridge, he will topple onto the line and, although he will die, his chunky body will stop the train, saving five lives. The question is, is it permissible to
The famous trolley problem describes a scenario where the train track has lost its breaks and is speeding up toward a junction. There are two pathways the train operator can take, either continue the current course, where five people are working on the rails, or switch to the alternative route, where only one person is situated. Taking either direction would result in casualties. The philosophers add an extra twist to the scenario by offering an alternative option: imagining that there is a bridge
