  • Acceleration of a Trolley

    958 Words  | 2 Pages

    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]=

  • Trolley Investigation

    1738 Words  | 4 Pages

    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

    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

  • The Trolley Problem, by Judith Jarvis Thomson

    756 Words  | 2 Pages

    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

  • Investigation of the Speed of a Trolley Down a Ramp and Its Gradient

    944 Words  | 2 Pages

    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

  • Investigating the Effect of Mass and Speed of a Moving Object on Its Stopping Time

    2196 Words  | 5 Pages

    the mass of a moving object – a trolley, affects its stopping distance. [IMAGE] [IMAGE] Stopping Distance m In order for a moving vehicle to stop a Braking Force is needed. The friction between the wheel and the ground usually does this. But in this experiment the trolley has no brakes therefore a weight is attached to the trolley to stop it when the string attached to the weight tightens and provides an opposing force to the movement of the trolley. Force is the factor that pushes

    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

  • Investigation of Energy Stored in a Spring

    1353 Words  | 3 Pages

    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 was then compressed and then released, as

    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 experiment energy will be transferred into many forms but no energy will be lost or gained. As the trolley is raised it gains potential energy, when released down the ramp this energy is converted to kinetic energy. When the trolley hits the horizontal surface all the energy

    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

    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

    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...

    Thought experiments such as The Trolley Problem can help give insight into how people make moral decisions and from there, what they rely on to make the decision. In the first situation of The Trolley Problem, you could pull a switch and kill one person instead of five. Here most people would pull the switch. However, in the second situation you would push someone off of a bridge to stop the trolley before it reached the five other people. In the second situation

    assign to pushing someone in front of a trolley versus throwing oneself in front of a trolley. We posit that these actions have the same moral value through a utilitarian lens, but since common moral sense dictates that these actions do not have equal moral weight, utilitarianism must, therefore, be an incorrect philosophy.
