(A) Introduction This report is the analysis of the motion of a Slinky dropping. When a slinky is fully extended and then released, it can be seen that the top and bottom of the slinky act somewhat unusually and do not fall at an acceleration of 9.81 m/s. In order to understand this motion, a video tracking software has been used to track these two points of the slinky. This report focuses on the y-direction (vertical) movement of these points through two phases. Phase A to B is when the top of the slinky has yet to meet the bottom of the slinky. When the slinky is fully compressed, this is when phase B to C begins, and it ends when the slinky hits the floor. The aim of this report is to analyse these results, in order to explain the movement of the falling slinky.
(B) Procedure In this experiment, a 21cm ruler has been used for a reference length for the video tracking software. For increased accuracy, a longer reference length should be used.
The procedure, which should be recorded using a camera on a tripod stand, placed such that there is no perspective error, is as follows: 1. Hold slinky from the top most coil so that it is fully extended and does not touch the floor. (See Diagram B1) 2. When the slinky has settled and there is minimal movement, release the slinky. 3. Stop recording when the Slinky has come to a complete rest. The height that the Slinky is released from is unimportant, as the video tracking software is able to calculate this through the reference length. The Slinky should be coloured differently from its background, with the top and bottom of the slinky brightly coloured so that it is easily distinguishable for accurate tracking. In this experiment, a high-speed camera should be used with a tripod to minimize any shakiness and for optimum accuracy.

Falling and Mobility

...Falling and Mobility Grand Canyon University NRS 433V Falling and Mobility Individuals with stroke are at risk for falls. Patient safety and their general wellbeing in all areas of health care setting is worldwide concern. The major cause of medical hurdle following acute stroke are falls, and it constitutes a significant health concern throughout the post stroke lifetime. Age, chronic disease or sudden disability like stroke puts the elderly people at risk. However, stroke survivors are at greater risk of falling specifically while walking or with activities of daily living. The use of assistive devices such as walker, cane, and wheelchair to increase their function also puts them at risk when not used correctly (Nazarko, 2012). Stroke survivors and their caregivers have several ideas with regards to mobility and fall instances. The experiences of stroke survivors and their caregivers towards fall and mobility is critically analyzed using a qualitative study in this paper (Kelley, 2010). According the reviewed article falling and Mobility Experience of Stroke Survivors and Spousal caregivers’, the clinical problem leading to this study as identified by the authors is the stroke survivors’ high risk for fall while performing walking or performing activities of daily living. Complete or partial disability as a result stroke has been linked to high risk for fall. The authors noted that limited studies exist about stroke survivors and caregivers issues of falling or general...

Falling in Love

...FALLING IN LOVE BY: ANONYMOUS When you think of your past love, you may view it as a failure. But when you find a new love, you view the past as a teacher. In the game of love, it doesn't really matter who won or who lost. What is important is you know when to hold on and when to let go! You know you really love someone when you want him or her to be happy, even if his or her happiness means that you're not part of it. Everything happens for the best. If the person you love doesn't love you back, don't be afraid to love someone else again, for you'll never know unless you give it a try. You'll never truly love a person you love unless you RISK FOR LOVE. Love strives in hurting. If you don't get hurt, you don't learn how to love. Love doesn't hurt all the time, though the hurting is still there to test you and to help you grow. Don't find love, let love find you. That's why it's called falling in love because you don't force yourself to fall. You just fall. You cannot finish a book without closing its chapters. If you want to go on, then you have to leave the past as you turn the pages. Love is not destroyed by a single failure nor won by a single caress. It is a lifetime venture in which we are always learning, relearning, discovering, rediscovering, and growing. The greatest irony of love is LETTING GO WHEN YOU WANT TO HOLD ON and HOLDING ON WHEN YOU NEED TO LET GO. We lose someone we love only when we are destined to find someone else who can love us even more than we can......

...Name ____________________________________ Motion in 2D Simulation Go to and click on Run Now. 1) Once the simulation opens, click on ‘Show Both’ for Velocity and Acceleration at the top of the page. Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around. When Velocity ends(stop dragging), acceleration reduces. Acceleration decreases right before velocity peaks. The vector for acceleration always appears to be at a right angle. 2) Which color vector (arrow) represents velocity and which one represents acceleration? How can you tell? Velocity is green and acceleration is blue. When velocity is constant or close to 0 acceleration declines 3) Try dragging the ball around and around in a circular path. What do you notice about the lengths and directions of the blue and green vectors? Describe their behavior in detail below. Both are equal when moving around in a circular path. Velocity seems to increase and decrease very little and the acceleration remains the same 4) Now move the ball at a slow constant speed across the screen. What do you notice now about the vectors? Explain why this happens. When moving slow and steady, there is barely any acceleration. Velocity is the measurement of speed/direction, and acceleration is the change of. 5) What happens to the vectors......

...Tobi Gonzalez 2/25/13 Motion is Relative 1. The two units of measurement are distance and time. 2. The kind of speed is registered by an automobile speedometer is instantaneous speed. 3. Average speed is the speed averaged over duration of time. Usually the total distance covered divided by the total time. Instantaneous speed is the speed given at that instant within that span of time, measured with a real time speedometer. 4. The average speed in kilometers per hour for a horse that 
gallops a distance of 15 km in a time of 30 min is: Average speed = 15 km/30 min = 15 km/0.5 h = 30 km/h 5. Speed is the distance covered per unit of time. Acceleration is the rate in which an object changes its velocity. 6. If a car is moving at 90 km/h and it rounds a corner, also at 90 km/h, 
it does maintain a constant speed but not a constant velocity. The velocity never changed, only the direction it’s traveling. 7. Velocity is change in displacement, change in position over a period of time, while Acceleration is change in velocity over a time period. 8. The acceleration of a car that increases its velocity from 0, to 
100 km/h in 10s is 10km/h*s 9. The acceleration of a car that maintains a constant velocity of 
100 km/h for 10s is 0 km/h*s. Some of my classmates get this question wrong but the last question right because they fail to read the question. In the last question there was a change in velocity. However in this question there was no change in...

Research in Motion Analysis

...George Leong B.Comm.: Research In Motion Limited (NASDAQ:RIMM) appears to be rising from the ashes, as investors dive back into the stock of the once-fabled maker of the “BlackBerry.” For Research In Motion (RIM), it has been quite the journey after the investment community, including myself, thought the end was near for this former Wall Street star. Since the emergence of Apple Inc. (NASDAQ:AAPL), the BlackBerry and RIM’s “Playbook” tablet have proved to be horrible failures, based on my stock analysis. But something strange is happening in the equities market, as RIM has surged 168% since trading at $6.43 on September 21, 2012; Apple, on the other hand, has declined 29% in the same period, according to my technical analysis. My stock analysis shows an opening gap on the RIM stock chart on January 22 on a bullish moving average convergence/divergence (MACD) as indicated by the circles; while this is bullish, be wary of the stock’s overbought condition. Chart courtesy of The smartphone and tablet markets continue to be extremely competitive, and I expect this competition will heat up further, based on my stock analysis. My stock analysis suggests that Apple dominates the tablet market, but there is strong competition from Google Inc.’s (NASDAQ:GOOG) “Nexus” tablet and Samsung Electronics Co. Ltd.’s “Galaxy” series. (Read “Why Apple Needs to Refocus Its Energy.”) Some believers are also surfacing as RIM gets ready to launch new its new line of......

Falling Man

...Falling man The “Falling man” follows Keith, a few-and-thirty-year-old New Yorker who works in a real estate company in the World Trade Center. He also works in the World Trade Center when the attack happens the 11th September - but he is lucky and gets out of the first tower before it collapses. Hurt and confused he goes home to Lianne, Keith’s exwife and wants to get back together with her. They resume their in disjointed fragments, a form of cohabitation. The novel is, especially in a non-US context, an interesting description and interpretation of what the terrorist attacks meant for the New Yorker’s self-understanding. The terrorist attack splits, like the kind of catastrophic events tend to make the world into a before and an after. “It was no longer a street, but a world, a time and space of falling ash and near night. (...) The roar was still in the air, the fall along curved rumbling. This was the world now. ..” The downfall, the catastrophic dust chaos, is in the novel structure also a new beginning, and Keith's appearance in Liannes doorway is a violent return from the dead: "When he stood in the doorway, it was not possible, a man come out of an ash storm, nothing but blood and slag, which stank of something burnt, with pinpoint glimpses of shattered glass in his face." Keith's return after the terrorist attacks becomes a crucial event that puts the protagonists' lives upside down. But unlike the traditional magazine layout of such experiences where they......

...Motions: * Politics This House would grant politicians immunity from prosecution PROS Giving politicians’ immunity from prosecution allows them to focus on performing their duties The premier reason that most states, even those that allow for the prosecution of politicians, abstain from prosecuting them while they hold office is that being a politician is a job that requires one’s undivided attention.  Especially for the holders of prominent national-level offices, writing legislation, responding to crises under one’s purview, consulting one’s constituents, and engaging in campaign work often lead to politicians working an upwards of 12 hour day, every day.  To expect politicians cope with all of these concerns will simultaneously constructing a defense against pending charges would be to abandon all hope of them serving their constituents effectively.  We are rightly aggravated when politicians take extensive vacations or other extracurricular forays. Being under indictment not only consumes even more of a politician’s time; the stress it causes will inevitably seep into what remaining time they do allocating to fulfilling their duties, further hindering their performance.  The impeachment proceedings for Bill Clinton on charges of perjury and obstruction of justice were so intensive that they took tremendous resources away from not only the president himself, but all branches of the federal government for several months, amidst serious domestic and foreign...

Falling in Love

...Name: Instructor: Title: Date due: Falling in Love It is intriguing how two strangers can get to know each other and seem like they were never apart. It is the basis of what marriage often refers to becoming one in body and soul. The reason behind all this is falling in love. Falling in love is used in the context of romantic relationships. It is a Western ideology that describes shifting away from a feeling of being neutral as a person to close intimate and emotional attachment to another person, usually of the opposite sex. The term is used to explain a process of interaction and understanding the inner most aspects of a person. It later grows into acceptance of the person’s positive and negative attributes. The feeling of ‘love’ eventually grows strong. When the term ‘fall’ is used, it means that falling in love is an irreversible, uncontrollable and risky affair. It makes the so called victim be in a situation where they are vulnerable. It is a strong longing and desire to be with the other person, without a credible explanation as to why they would want to do that. It makes it seem as if the person is falling in a trap. There are certain factors that enhance the process of falling in love. They include proximity to each other, having similar tastes and preferences, reciprocity where the love given is received in equal measure and being physically attractive. Medically, there is narcissistic identification that occurs when people fall in love. For instance,......

Motion Analysis

...Campbell Messner HPEZ 373 4/8/14 Motion Analysis Report: Hockey Slap Shot The hockey slap shot is a complex movement involving many different joints and muscles. In game situations the hockey slap shot is usually used by defenseman, but can be utilized successfully by forwards as well. There are six phases to a hockey slap shot: backswing, downswing, pre-loading, loading, release, and follow through. The hockey slap shot is most of the time made with a carbon fiber hockey stick that has a pre-determined amount of “flex” to the stick to get the puck moving at such high velocities. Accuracy of the puck placement usually depends of whether or not the puck is struck in the loading portion of the swing or in the release portion of the swing. The follow through is also important when determining placement. Unlike most primary sports movements, the hockey slap shot is a dynamic movement where the player is moving along the ice while striking the puck. This is what allows the slap shot to be so dangerous and interesting. To begin a slap shot a player must place the puck at around the middle of their stance for best power. The first movement of the slap shot is the backswing. Depending on which side the player stick handles, right or left, the dominant hand will be first on the stick and the non-dominant placed further down the stick. For the rest of the analysis we will use a player with a left-handed shot. In the backswing of the shot this is where the kinetic energy is......

Uniformly Accelerated Motion: Free Fall

...EXPERIMENT #6: UNIFORMLY ACCELERATED MOTION: FREE FALL INTRODUCTION: A free falling object is an object that is falling under the sole influence of gravity. Any object that is being acted upon only by the force of gravity is said to be in a state of free fall. It is a motion of a body where its weight is the only force acting upon it. Our objective in this experiment is to measure the acceleration of a falling object assuming that only force acting on the object is the gravitational force. THEORY: As an object falls freely, it accelerates due to the applied net force. One equation of motion for a body starting from rest and undergoing constant acceleration can be expressed as: d = ½ at2 where d is the distance the object travelled from its starting point, a is the acceleration of the object, and t is the time elapsed since the motion began. PROCEDURE: Materials needed are: * Free fall apparatus * Small and Large metal ball * Smart timer * Clamp rod * Meter stick So first we measured the height of the release mechanism into 50 cm with the use of meter stick. In trial 1, we used small metal ball. Mounted the free fall adapter’s release mechanism horizontally in the clamp. We place the free fall adapter’s timing pad on the table directly below the release mechanism. We placed the metal ball in the release mechanism and pressed the spring loaded rod inward to hold the ball in the mechanism, and tighten the thumbscrew to hold the rod in place.......

Motion Analysis

...Nic Juister Motion Graphics 2-18-15 Professor Tanya Cummings “Motion Analysis: Title Sequence” True Detective Main Title Sequence: I chose True Detective’s main title sequence because it portrayed a style that I had never really seen before in motion. It contains photographic double exposure which have always peaked my interested with photography. However, Antibody studios took fragmented portraits, created using human figures as windows into partial landscapes, and gave them new meaning to show how characters are marginalized or internally divided through the double exposure. The double exposure photography combined with movement of film in a different opacity creates interesting compositions with formal and informal balance. Even though there isn’t much motion or special effects in the piece the viewer experience is not effected in anyway. The contrasting balance between large double exposure photographs with unknown content and minimal typography make the viewer want more, which is exactly what an opening title sequence should do. Keeping the viewer invested is the most essential element of a successful title sequence and this piece does just that. The opening title sequence sets the tone and mood for the TV show. True Detective is a thriller murder mystery that is dark and twisted and the grungy dark textures combined with the double exposures in contrasting space embody the feeling of the show. I believe True...

Francis March 20, 2015 Introduction Research In Motion (RIM) began in 1984 with two School of Engineering students from Canada, Mike Lazaridis President and Co-CEO (University of Waterloo) and Douglas Fregin Vice President of Operations (University of Windsor). These two young men had ambition and vision that translated into success. RIM became the first to market in the wireless data technology industry. From 1988 through 2006 they produced a number of Award winning products in the Wireless Data Communication Technology Industry that kept them on the cutting edge of Information Technology and Innovation. Challenges Faced by RIM RIM became an industry giant faced with producing continued innovative products in the rapidly changing environment of Wireless Data Communications in the field of Information Technology. They grasped a large share of the market with the creation and continued development of the Black Barry their most famous product and its’ technology. They had to forecast the future in order to meet market demands and reserve resources while keeping up with the competition during a time of rapidly changing technology. In 2005 the company learned a real lesson relative to filing and protecting the patients for their creations. They became victims of injustice when they were ordered to pay $612.5 million to New Technology Products (NTP) which doesn’t actually make or sell anything relative to the......

Falling in Love

... Falling in Love It's like the feeling you get when you stand in an azure world then you fall off the cliff with your eyes closed, the wind on your face and the euphoria of flying filled up your senses. It will be the most understatement of the year when I say that it is just a simple feeling created by the mind, believed by the heart and followed by the soul for in reality, it is exhilarating to say the least, the most powerful drug ever devised by nature for humankind. Nothing could ever compare to it, the sense of utter bliss that wraps one in an embrace so tight and so fast you feel like you can almost do anything. It comes without warning, it hits in an unexpected way and always catches one unaware in an unguarded moments that often times it wreaks the worst havoc before one can come to terms with it. And there is no telling when it would strike. An ordinary day in any time of the world, a smile, a whiff of perfume wafting in the air, an accidental momentary meeting of the eyes, a simple conversation and then it grabs you. And it fills you, gives your feet wings your mind is tricked into the impression that you can actually fly. It fools the senses. The eyes become clear and dewy at the same time, giving it a strange sparkle that eludes explanation from even the well- versed human biology. The cheeks become flushed with color and warmth which not even the coldest winds of December could ever dampen. The body has gone haywire because of the......
