SPH4U-B 4 Circular Motion Physics SPH4U-B Lesson 4 Introduction Transportation has undoubtedly advanced. Not only have vehicles changed‚ but the means by which people can get themselves to and from different locations has changed as well. Maps and compasses now take a backseat to the Global Positioning System (GPS). Access to the GPS is now very widespread; 24 satellites above our atmosphere are used to send and receive information in order to accurately determine locations of

Ethical Reasoning In ethical reasoning‚ the Trolley Problem is an excellent example of what most people find to be ethical and unethical. Unfortunately‚ there is really no right answer. However‚ the most common answers to the two Trolley Scenarios are: it is ethical to pull the lever‚ but it is unethical to push the very large person. In the scenario of having to pull the level and kill one person verses killing five people‚ most people’s reaction is to pull the level. This was also my reaction

Week 1-Discussion 1-Circular Flow Diagram To first explain how the circular flow diagram relates to the current economic situation‚ one must realize that the two‚ three‚ and four sector models no longer apply to the United States any more. Only the five sector model currently applies. The five sector model of the circular flow of income is a more realistic representation of the economy and has a more definitive look as to what and how economics really is in the world. In the more simplistic two

Circular Flow Diagrams Introduction Money flows into and out of the economy. The circular flow diagram explains how money moves through the economic system involving households‚ businesses‚ the government‚ and foreign agents (Editorial Board‚ 2011). Circular flow diagrams are visual models that show firms who employ workers‚ the workers then spend on goods produced by firms‚ and the money is then used to compensate the worker and buy raw materials to make the goods and the circle continues.

A carousel‚ or merry-go-round‚ is an amusement ride consisting of a rotating circular platform with seats for riders. The "seats" are traditionally in the form of rows of wooden horses or other animals mounted on posts‚ many of which are moved up and down by gearwork to simulate galloping to the accompaniment of looped circus music

MOTION: FERRIS WHEEL I. INTRODUCTION In this group project‚ we’ve decided to use a Ferris Wheel as an object to represent Uniform Circular Motion. A Ferris is a non-building structure consisting of a rotating upright wheel with passenger cars attached to the rim in such a way that as the wheel turns‚ the cars are kept upright‚ usually by gravity. Some of the largest and most modern Ferris wheels have cars mounted on the outside of the rim‚ and electric motors to

centripetal acceleration. Centripetal force means “center seeking.” It is the force responsible for keeping an object in circular motion. If there were no centripetal force the object would fly off at a tangent because of Newton’s First Law. This is demonstrated by spinning an object on a string. If the string were to break or be cut‚ the object would fly out of its circular path at a tangent. An equation can be used to represent the relationship between centripetal force‚ mass‚ velocity‚ and

1. Introduction Moral reasoning is defined as “individual or collective practical reasoning about what‚ morally‚ one ought to do”. The theory introduces two moral principles: consequentialist principle‚ which determines an act’s morality by its consequences‚ and categorical principle‚ which assesses an act by looking at its certain duties and rights despite the outcomes. To some extent‚ these two principles seem to contradict each other‚ which may become obstacles for achieving reasonable actions

Speed and Radius Question For an object moving with uniform circular motion‚ what relationship exists between the radius of its path and its speed? Hypothesis If the radius is increased‚ I believe that the speed will decrease‚ giving speed and its radius an inverse relation. Variables The variables in this lab are the radius of the circular path‚ mass of the rubber stopper‚ mass of the hanging weight‚ number of revolutions‚ elapsed time‚ period‚ and speed.

Time of Flight - Hohmann To calculate time of flight for the payload travelling between Earth and Mars‚ some assumptions are made. It will be assumed that Earth and Mars have circular orbits. In actuality‚ they have elliptical orbits‚ but with a very low eccentricity. Eccentricity is a ratio that measures how circular an ellipse is. An eccentricity value of 0 denotes a perfect circle. In this report‚ it is assumed that Earth and Mars have an eccentricity of 0. It is also assumed that Earth and
