If it takes 0. Possible Answers: Correct answer: Explanation: To solve this problem, we need to consider the change in the ball's momentum. To do so, we'll use the following equation. Rearrange the above equation to solve for the average force. To do so, he bends his knees and produces an upwards force that results in a constant upward net force of N. If Joe experiences this force for 0. Possible Answers: Correct answer: Explanation: To solve this problem we need to use the relationship between force and impulse, which is given by the following equation: This equation represents that the rate of change of momentum with respect to time is equal to the net force that causes said change in momentum. Thus: Note that Joe must have an initial velocity of before he begins to apply the upwards Force that accelerates him upwards, therefore our equation simplifies to: Solve for Report an Error Example Question 1 : Impulse And Momentum Which of the following explains why when we land on our feet, we instinctively bend our knees?- Hint: think about the relationship between force, impulse, and time. Possible Answers: By bending our knees we extend the time it takes us to stop, which increases the impact force By bending our knees we extend the time it takes us to stop, which diminishes the impact force When we bend our knees we extend the time in which we apply the force that stops us, so our impulse is smaller By bending our knees we use a greater force to stop, which makes the impulse smaller When we bend our knees we extend the time in which we apply the force that stops us, so our impulse is greater Correct answer: By bending our knees we extend the time it takes us to stop, which diminishes the impact force Explanation: Say that, when we hit the ground, we have a velocity , which is predetermined by whatever happens before the impact. When we hit the ground you will experience a force for some time.

This force will cause the acceleration that reduces our velocity to zero and gets us to stop. Note that, regardless of how much time it takes us to stop, the change in momentum impulse is fixed, since it directly depends on how much our velocity changes: since we come to a stop Note that the initial momentum does not depend on the impact force nor on how much time it takes to stop. The initial momentum depends on the velocity we have when we first hit the ground. This velocity is given by whatever happened before we hit the ground, which no longer concerns us since we only care about what happens from the moment we first hit the ground till the moment we stop. Yes, the time that passes for you to stop is very small, but it is impossible for it to be zero. So we have that the change in momentum impulse is a constant: , since is predetermined.- Remember that any change in momentum for a given mass occurs because its velocity changes. The velocity of the mass changes due to an acceleration and an acceleration is caused by a force. This gives us a relationship between force and impulse: In our scenario, would be the impact force that stops us and the time it takes us to stop. From the equation above, it is easy to see that, since is fixed, when gets larger gets smaller, and the other way around. Therefore, we bend our knees to effectively increase the time it takes us to stop. Thus, diminishing the impact force as to avoid hurting ourselves.
- According to Sayre what are the three steps in the process of "seeing"? The use or study of these symbols is called: iconography. Which of these statements best defines visual literacy? The terms naturalistic or realistic art are sometimes used to describe representational art. In a work of art, "content" refers to what the work expresses or means.

They should educate the public about the value of art. They have little context in which to view the work. Richard Serra In Chapter 3, Sayre discusses two ways of valuing art. What are they? They're opposed to each other; form is the literal shape and mass whereas content is the meaning of an image. The literal, visible image in a work of art, as distinguished from its content, which includes the connotative, symbolic, and suggestive aspects of the image.- The number of alternatives can vary among items as long as all alternatives are plausible. Plausible alternatives serve as functional distractors, which are those chosen by students that have not achieved the objective but ignored by students that have achieved the objective. There is little difference in difficulty, discrimination, and test score reliability among items containing two, three, and four distractors. Additional Guidelines 1. Avoid complex multiple choice items, in which some or all of the alternatives consist of different combinations of options. Keep the specific content of items independent of one another. Savvy test-takers can use information in one question to answer another question, reducing the validity of the test. Finally, designing alternatives that require a high level of discrimination can also contribute to multiple choice items that test higher-order thinking.

Post-Renaissance Meaning of Art The emergence of the great European academies of art reflected the gradual upgrading of the subject. New and enlightened branches of philosophy also contributed to this change of image. By the midth century, the mere demonstration of technical skills was insufficient to qualify as art - it now needed an "aesthetic" component - it had to be seen as something "beautiful.
- Thus, by the end of the 19th century, art was separated into at least two broad categories: namely, fine art and the rest - a situation that reflected the cultural snobbery and moral standards of the European establishment. Furthermore, despite some erosion of faith in the aesthetic standards of Renaissance ideology - which remained a powerful influence throughout the world of fine art - even painting and sculpture had to conform to certain aesthetic rules in order to be considered "true art". Meaning of Art During the Early 20th Century Then came Cubism , which rocked the fine arts establishment to its foundations. Not simply because Picasso introduced a non-naturalistic branch of painting and sculpture, but because it shattered the monotheistic Renaissance approach to how art related to the world around it.
- In fact, one might say that from this point "art" started to become "indefinable". The decorative and applied arts underwent a similar transformation due to the availability of a vastly increased range of commercial products. However, the resultant increase in the number of associated design and crafts disciplines did not have any significant impact on the definition and meaning of art as a whole. This new American orientation encouraged art to become more of a commercial product, and loosen its connection with existing traditions of aestheticism - a trend furthered by the emergence of Abstract Expressionism, Pop-Art, and the activities of the new breed of celebrity artists like Andy Warhol.
- All of a sudden, even the most mundane items and concepts became elevated to the status of "art". Under the influence of this populist approach, conceptualists introduced new artforms, like assemblage, installation, video and performance. In due course, graffiti added its own mark, as did numerous styles of reinterpretation, like Neo-Dada , Neo-Expressionism , and Neo-Pop, to name but three. Schools and colleges of art throughout the world dutifully preached the new polytheism, adding further fuel to the bonfire of Renaissance art traditions. Postmodernism and the Meaning of Art The redefinition of art during the last three decades of the 20th century has been lent added intellectual weight by theorists of the postmodernist movement. According to the postmoderns, the focus has shifted from artistic skill to the "meaning" of the work produced. In addition, "how" a work is "experienced" by spectators has become a critical component in its aesthetic value.
- The phenomenal success of contemporary artists like Damien Hirst, as well as Gilbert and George, is clear evidence in support of this view. For more about experimental artists, see: avant-garde art. A Working Definition of Art In light of this historical development in the meaning of "art", one can perhaps make a crude attempt at a "working" definition of the subject, along the following lines: Art is created when an artist creates a beautiful object, or produces a stimulating experience that is considered by his audience to have artistic merit.

This is simply a "working" definition: broad enough to encompass most forms of contemporary art, but narrow enough to exclude "events" whose "artistic" content falls below accepted levels. In addition, please note that the word "artist" is included to allow for the context of the work; the word "beautiful" is included to reflect the need for some "aesthetic" value; while the phrase "that is considered by his audience to have artistic merit" is included to reflect the need for some basic acceptance of the artist's efforts. For centuries, if not millennia, people have been emotionally affected - sometimes overwhelmed - by works of art: from Greek Sculpture , to Byzantine architecture, the stunning creativity of Renaissance and Baroque Old Masters like Donatello, Raphael and Rembrandt, and famous painters of the modern era, like Van Gogh, Picasso and Auguste Rodin.- Poetry, ballet and films can be equally uplifting. So while we may not be able to explain precisely what art is, we cannot deny the impact it has on our lives - one reason why public art is worth supporting. The very essence of creativity means it cannot be defined and pigeon-holed. Any attempt at doing so, will quickly become out-of-date and thus pointless, even counter-productive. What happens, for instance, if an artist produces something that by popular consensus is "art", but isn't accepted as such by the arts establishment?

It's worth remembering that we still can't define a "table" or an "elephant", but it doesn't cause us much difficulty! It's fair to say that someone educated in the values of Renaissance art, and who therefore has a reasonable understanding of traditional painting, is less likely to regard postmodernist installations as art, than a person without such an understanding. Similarly, a person who loves TV and thinks museums are generally rather boring and unexciting places, is more likely to be impressed with contemporary video art than someone else who is comfortable with traditional museum exhibitions. Because of this, one might say that a person's attitude to art says more about his or her personal values, than the art itself. Who Has the Right to Define Art? Since no consensus among art critics as to the meaning of art is likely to emerge anytime soon, which set of "experts" should be allowed to take charge: Artists, sociologists, historians, lawyers, philosophers, archeologists, anthropologists, or psychologists?The Creative Impulse Introduction To The Arts 8th Edition Sporre Test Bank
After all, the world is full of so-called "experts" - structuralists, proceduralists, functionalists, as well as the usual crop of political theorists like Marxists and so on - who can't agree on what counts as art. So who do we give the job to? How is Art Classified? Traditional and contemporary art encompasses activities as diverse as: Architecture, music, opera, theatre, dance, painting, sculpture, illustration, drawing, cartoons, printmaking, ceramics, stained glass, photography, installation, video, film and cinematography, to name but a few.- All these activities are commonly referred to as "the Arts" and are commonly. Disagreement persists as to the precise composition of these categories, but here is a generally accepted classification. Fine Arts This category includes those artworks that are created primarily for aesthetic reasons 'art for art's sake' rather than for commercial or functional use. Designed for its uplifting, life-enhancing qualities, fine art typically denotes the traditional, Western European 'high arts', such as:.

Print The world of the preschooler is one of imagination and magic. For many children, their creativity will reach its peak before the age of six, after which it will begin to decline with the onset of formal schooling and the developmental drive towards conformity. The three year old discovers that he can place blocks in an arrangement, or scribble lines on a paper in way that represents an object or action. His fine motor skills are developed enough that he can control writing utensils or manipulate objects with more precision, which develops further over the preschool years. Children this age begin to create with intention — purposefully drawing a monster or a flower. By the time they are 5, many children add details and annotate with words and narrated stories. They love pretend games and have a natural tendency to fantasize, experiment, and explore.- They are fascinated with magic and struggle to distinguish between fantasy and reality. However, their creative drive ignites a desire to learn and supports intellectual development across all subjects. Supporting divergent thinking means providing activities that allow for child appropriate inquiry, reflection, wondering, curiosity, and even supported confusion. Divergent thinking, and hence creativity and creative problem solving, are more than art — it is thinking, predicting, imagining, and creating.
