Energy Definition and Examples
Energy is defined as the capacity of a physical system to perform work. However, its important to keep in mind that just because energy exists, that doesnt meanà its necessarily available to do work. Forms of Energy Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. Heat - Heat or thermal energy is energy from the movement of atoms or molecules. It may be considered as energy relating to temperature.Kinetic Energy - Kinetic energy is the energy of motion. A swinging pendulum has kinetic energy.Potential Energy - This is energy due to an objects position. For example, a ball sitting on a table has potential energy with respect to the floor because gravity acts upon it.Mechanical Energy - Mechanical energy is the sum of the kinetic and potential energy of a body.Light - Photons are a form of energy.Electrical Energy - This is energy from the movement of charged particles, such as protons, electrons, or ions.Magnetic Energy - This form of energy results from a magnetic field.Chemical Energy - Chemical energy is released or absorbed by chemical reactions. It is produced by breaking or forming chemical bonds between atoms and molecules.Nuclear Energy - This is energy from interactions with the protons and neutrons of an atom. Typically this relates t o the strong force. Examples are energy released by fission and fusion. Other forms of energy may include geothermal energy and classification of energy as renewable or nonrenewable. There may be overlap between forms of energy and an object invariably possesses more than one type at a time. For example, a swinging pendulum has both kinetic and potential energy, thermal energy, and (depending on its composition) may have electrical and magnetic energy. Law of Conservation of Energy According to the law of conservation of energy, the total energy of a system remains constant, though energy may transform into another form. Two billiard balls colliding, for example, may come to rest, with the resulting energy becoming sound and perhaps a bit of heat at the point of collision. When the balls are in motion, they have kinetic energy. Whether they are in motion or stationary, they also have potential energy because they are on a table above the ground. Energy cannot be created, nor destroyed, but it can change forms and is also related to mass. The mass-energy equivalence theory states an object at rest in a frame of reference has a rest energy. If additional energy is supplied to the object, it actually increases that objects mass. For example, if you heat a steel bearing (adding thermal energy), you very slightly increase its mass. Units of Energy The SI unit of energy is the joule (J) or newton-meter (N * m). The joule is also the SI unit of work.

Health Care System Of The United Kingdom Essay - 1674 Words
Introduction: Health is the faculty to live a full, functioning and conscious life, which is the result of a composite interaction between our genetic, the atmosphere we live in, and the culture we are a part of.

Every health care system composed of two broad sections; one focused on strategy and organization and the other is the definite medical and or clinical care, which is also divided into primary (community care, practitioners, Dentists, Pharmacists), secondary (Hospital-based care), and tertiary care (specialist hospitals). According to the World Health Organization rankings, France ranks first and the United Kingdom ranks eighteenth amongst a hundred and ninety different countries. The French love their health care system and there is also a lot that much of the world can learn from France. Towards the end of world war two the French realized that their country was in a pretty bad shape.

Hamlet Monologue Essay Example For Students
Hamlet Monologue Essay A monologue from the play by William Shakespeare HAMLET: O, what a rogue and peasant slave am I! Is it not monstrous that this player here, But in a fiction, in a dream of passion, Could force his soul so to his own conceit That from her working all his visage wanned, Tears in his eyes, distraction in his aspect, A broken voice, and his whole function suiting With forms to his conceit? And all for nothing, For Hecuba! What\s Hecuba to him, or he to Hecuba, That he should weep for her? What would he do Had he the motive and the cue for passion That I have? He would drown the stage with tears And cleave the general ear with horrid speech, Make mad the guilty and appal the free, Confound the ignorant, and amaze indeed The very faculties of eyes and ears. Yet I, A dull and muddy-mettled rascal, peak Like John-a-dreams, unpregnant for my cause, And can say nothing. No, not for a king, Upon whose property and most dear life A damned defeat was made. Am I a coward? Who calls me villain? breaks my pate across? Plucks off my beard and blows it in my face? Tweaks me by the nose? gives me the lie i\ the throat As deep as to the lungs? Who does me this? Ha, \swounds, I should take it, for it cannot be But I am pigeon-livered and lack gall To make oppression bitter, or ere this I should ha\ fatted all the region kites With this slave\s offal. Bloody, bawdy villain! Remorseless, treacherous, lecherous, kindless villain! O, vengeance! Why, what an ass am I! This is most brave, That I, the son of a dear father murdered, Prompted to my revenge by heaven and hell, Must like a whore unpack my heart with words And fall a-cursing like a very drab, A stallion! Fie upon\t, foh! About, my brains. Hum I have heard that guilty creatures sitting at a play Have by the very cunning of the scene Been struck so to the soul that presently They have proclaimed their malefactions. For murder, though it have no tongue, will speak With most miraculous organ. I\ll have these players Play something like the murder of my father Before mine uncle. I\ll observe his looks. I\ll tent him to the quick. If \a do blench, I know my course. The spirit that I have seen May be a devil, and the devil hath power T\ assume a pleasing shape, yea, and perhaps Out of my weakness and my melancholy, As he is very potent with such spirits, Abuses me to damn me. I\ll have grounds More relative than this. The play\s the thing Wherein I\ll catch the conscience of the king.
