Physics of Football Essay -- physics sport sports american football

Watching a weekend football game could be teaching you something other than who threw the most passes or gained the most yards. Football provides some great examples of the basic concepts of physics! Physics is present in the flight of the ball, the motion of the players, and the force of the tackles. This web page will show you how physics applies to these areas of football. What Exactly Is Physics and What Does It Have to Do with Football? When you throw a football across the yard to your friend, you are using physics. You make adjustments for all the factors, such as distance, wind and the weight of the ball. The farther away your friend is, the harder you have to throw the ball, or the steeper the angle of your throw. This adjustment is done in your head, and it's physics. Physics is the branch of science that deals with the physical world. The area of physics that is most relevant to football is mechanics, the study of motion and its causes. The three main categories of motion that apply to the game are: * delivery of a football through the air (pass, punt, kickoff, field goal, extra point) * runners on the field (backs, receivers, linemen) * stopping runners on the field (tackling, blocking) FLIGHT OF THE BALL When the football travels through the air (long pass, punt, kickoff, field goal), it always follows a curved, or parabolic, path because the movement of the ball in the vertical direction is influenced by the force of gravity As the ball travels up, gravity slows it down until it stops briefly at its peak height, the ball then comes down, and gravity accelerates it until it hits the ground. This... ... the amount of force applied: Less force is required farther out from the center of mass than closer in. So, by tackling a runner low -- far from the center of mass -- it takes less force to tackle him than if he were tackled high. Also, if a runner is hit exactly at his center of mass, he will not rotate, but instead will be driven in the direction of the tackle. Similarly, coaches often advise linemen to stay low. This brings their center of mass closer to the ground, so an opposing player, no matter how low he goes, can only contact them near their center of mass. This makes it difficult for an opposing player to move them, because they will not rotate upon contact. This technique is critical for a defensive lineman in defending his own goal in the "red" zone, the last 10 yards before the goal line.

Communication and interpersonal skills Essay

Understand how communication and interpersonal skills affect managerial performance in the workplace Evaluate how interpersonal skills and communication skills affect managerial performance 2.1It is self-evident that communication and interpersonal skills are crucial in the workplace. Good two-way communication is important to enable the flow of information in an effective way whether it be verbal or non-verbal. Good communication has a positive impact on the performance of the team including; everyone is clear what is expected from them, they receive good feedback and recognition of achievements which makes staff feel valued and boosts employee morale. The manager needs to be approachable and have a non-threatening manner so staff feel at ease when discussing any issues or concerns. Good interpersonal relations encourage open behaviour where everyone is working as a team and supporting each other with a common sense of purpose. When goals and objectives are clearly set, with colleagues feeling involved and motivated, it has the overall effect of connecting each staff member and enabling team work. All of this results in a much stronger performance from the organisation as a whole, delivering high quality dental care in a happy relaxed environment and inevitably It will be much more successful in achieving its goals Poor communication results in staff being unclear of objectives, de-motivated and giving the impression of disinterest or even arrogance. Failure to communicate effectively often leads to conflict and the spread of rumours can begin to circulate which can harm a business internally as well as externally. It would be impossible to achieve the practice’s goals and objectives if there is significant conflict in the workplace. Boredom and a negative attitude also influence an employee’s receptiveness to a message. Overall poor communication and interpersonal skills have an adverse and counterproductive effect. Provide an evaluation of two or more strategies to overcome barriers to effective managerial communication and interpersonal skills. 2.2 In a small practice with part-time team members there is a high possibility of communication failure for example; messages not being passed on at all or incorrectly, decisions made earlier in the week without involvement or reference to all colleagues. This may result in mixed perceptions or feelings of marginalisation. To overcome this barrier, staff meetings are to be held on dates where all staff can attend. If this is not possible the minutes of the meeting should be written out and forwarded on to the appropriate people. It is also important to seek feedback regularly to check the message has been conveyed in a clear and concise way. Forums and emails are an efficient mechanism for short, chatty updates. It is also a good method of quickly communicating messages to several people and allowing further discussion with feedback and input. Another communication barrier that could occur would be staff not being clear of tasks that have been set for them to do by the busy, Principal Dentist. If this is done in an ad hoc, informal manner the tasks may not be done in the correct way or simply keep being rolled forward. To help overcome this barrier, I would need to ascertain from the Principal exactly what is required and when. I would then devise a rigorous schedule with clear step-by-step guide on what needs to be achieved. I would negotiate with individuals and delegate specific tasks depending on the skills required. The schedule would record who has been made responsible and have a checklist to be signed against. This would be displayed in a prominent position for example the staff room or a whiteboard. Once the job has been completed I can then report back within the time frame that the Dentist requires.

Pre Marital Sex

There is no longer any stigma attached to pre-marital sex in our society. Pop stars do it, sports stars do it, and politicians do it. Teens nowadays too tend to have this perception that sex before marriage is acceptable and would not even bother the consequences of it. Yet, it is still a big NO to every human as it violates this inner reality, because unmarried people thereby engage in a life-uniting act without a life-uniting intent. Some of the couples who deeply fall in love with each other are willing to do anything just to be together with their own partner without thinking twice, just like what Tom and Barbara did.The worse thing is their intention is only for sexual purposes. Frankly speaking, there are better ways to express your love for someone you’re not married to. Sex is not the only solution to show love to your spouse. Besides that, sex is not entertainment. If you’re bored go to the cinema or play a computer game or go for a run – don’t mi suse something as important as sex just for a bit of mindless fun. That would be like hiring a Rolls Royce car just to pick up some shopping – a waste, a misuse of something precious, something that is far more important if used properly.Other people’s bodies are not just toys for us to play with and then discard. They never thought of their after effects on their acts. They may get along together, but it is never guaranteed that they can be ‘happily ever after’. They will be facing problems later on like having difficulties in paying rental fees and daily expenses they still do not have the ability to earn money at this young age. On the other hand, Barbara who takes birth control pills to prevent ovulation still may have the possibility to get pregnant since there is no assurance for it.Not only that, taking birth control pills will cause excessive vaginal bleeding if over dosage, rash, breast tenderness and sexual diseases. Statistics has shown us that 40 percent of women ages 20 to 25 have HPV, which can cause cancer and which, of course, is only one of many sexually transmitted diseases. That means a lot of men and women are spreading potentially deadly diseases and not protecting themselves or others. Her mental health will most likely be affected.They should be wise and focus more on choosing behaviour that respects oneself and one's current and possibly future relationship partners, prospective children, etc. I truly believe that none of us here support premarital sex. Women and men should have a virginity pledge before they get married. True love waits. If a boy or girl truly loves you, they will want the best for you. They will not want you to suffer fear of disease, unwanted pregnancy and the psychological difficulties of premarital sex. They will want to experience love with you only in the very best place of all – the love nest of marriage.

Military technology and strate essays

Military technology and strate essays Military technology and strategy There were many strategies and weapons used in fighting in war. As the different wars went on, the technology just evolved more and more. They became more convenient, easier to use, smaller, they took less time to load, and they were more advanced. As the men and women fought in the different wars, they knew more and more about the new weapons and the different strategies of the war. These strategies and new technologies seemed to help the men and women out during the war. They didnt necessarily seem to save more lives, they just help out with hiding and during battles Another strategy was where the troops would maneuver outside the battlefield so they could cover a larger area. This was known as a front or a theatreWhen the expanse has covered an entire country; the corresponding waging of war on the largest scale to secure national objectives is called "grand strategy. Another of the many strategies the North or Union had was the "Anaconda." This was a maneuver which surrounded the South, Confederacy, so that they could not export or import supplies. This worked for some time but then the South found ways of exporting and importing.The most popular strategy with the Northern press, the public, and political leaders called for a direct overland march in Richmond, Virginia, the Confederate Capital. They thought that if Richmond fell, this would demoralize the South and the war would end. With this plan, the South's largest gun factory, the Tredegar Iron Works in Richmond would be destroyed. Some of Lincoln's military advice argued that this would invite disaster. Not only did the army consist of untrained volunteers, but an over land attack on Richmond would mean crossing difficult terrain. An alternate strategy, based on the expectation of a longer war, would give them the time to train an army o...

Keeping a Writers Notebook

Keeping a Writers Notebook Keeping a Writers’ Notebook Keeping a Writers’ Notebook By Ali Hale If you’ve ever had aspirations towards fiction-writing, you’ve doubtlessly heard the advice to keep a notebook on you at all times, to jot down those elusive flashes of brilliance that come at the most inopportune moments. It’s definitely a good idea to have pen and paper to hand as much as possible – however, the discipline of keeping a writers’ notebook means more than just scribbling a few words when inspiration strikes. Writing every day One of the best uses for your notebook is to get into the habit of writing every single day. There are lots of different ways to approach this; some which have worked for me (not all at once) are: Write first thing in the morning Spend five minutes writing at some point in the morning, and five minutes in the afternoon Write just before going to bed Jot down some notes before starting on your â€Å"proper† writing session of the day Of course there’ll be days when you feel uninspired, when you have nothing you want to write about, or when you’re hectically busy. But if you’re going to stick with writing fiction long-term, it needs to become part of your daily life. What do you write about? Don’t be prescriptive about what goes in your notebook. Some people find it best to work in a deliberately â€Å"scrappy† book, so that they don’t feel constrained to only write down gems of wisdom – yes, moleskin notebooks may be hugely popular, but a 99 cent pad will be just as good a repository for your ideas. Some of the many types of writing filling my notebook are: To-do lists for writing sessions or writing days There’s a great sense of satisfaction in ticking things off or scoring them out. If a to-do list makes you feel uncomfortable and constrained, try instead keeping a â€Å"done† list and writing down tasks after you complete them. Brainstorming for competition entries I wrote two or three short stories every month last year, most of them aimed at competitions with a set theme. A notebook is a great place to begin the idea-generation process; I like mind-mapping, by jotting the theme in a central circle and scribbling different plot and character possibilities around the edge. Once you get beyond the first few trite storylines, some intriguing ideas start to emerge. Character sketches When taking part in NaNoWriMo last year, I wrote three or four page character biographies for each of my main characters. Keeping these in my notebook made it easy to find them whilst working on the novel – I wasted as little time as possible when needing to look up details of family backgrounds, hobbies and so on. Plot outlines Most writers find that some level of outlining helps, particularly when writing anything longer than a short story. A notebook can be an easy way to develop a plot from initial spark through potential variations to a scene-by-scene breakdown. Snatches of dialogue Imagined or overheard phrases can be safely stashed in your notebook for future use: they may be totally inappropriate for the project which you’re currently working on, but could be invaluable a week or two down the line. Reviewing your notes It’s just as important to go back over your notes as it is to write them in the first place. Set aside a chunk of time – half-an-hour if possible – weekly, and go over what you’ve written during the past seven days. Make a new entry to record any ideas that you definitely want to pursue. (You might find it helps to use a second notebook at this stage.) Don’t recycle or burn old notebooks; even if you’re sure that you’ll never want the notes contained in them, store them safely somewhere. They’ll make fascinating reading a year, or ten years, further into your writing career – you’ll be able to see how far you’ve come, and you may rediscover old ideas that you’d forgotten. And if you become famous, perhaps you’ll even end up selling them on e-bay†¦ Want to improve your English in five minutes a day?

Chapter questions - Essay Example Future challenges that demand continued and strengthened collaboration include the dynamic nature of health condition that identifies emergence of new complications, need for unity among players in the global health issues, and the factors â€Å"that have encouraged the development of public-private partnerships for health† (Skolnik 359, 360). The public-private partnership refers to a framework in which parties from both public and private sectors collaborate in efforts to ensure more effective health care. The partnership might be valuable because of its pooled interest and resources that can meet different needs that could not be met by the parties if they were to work independently within their sectors’ interest and resources. The private sector, for example, has resources but are not willing to venture into care initiatives with low returns an interest that exist in the public sector. The partnership pools the sector’s interests and resources (Skolnik 350). Addressing the problems requires cooperative action because the problems affect wider regions and across international borders and only collaborative efforts across all the affected regions can tackle the problem comprehensively (Skolnik
