Playground Slide
Playground slides are found in parks, schools, playgrounds and backyards. The slide is an example of the simple machine known as the inclined plane, which makes moving objects up and down easier, or in this case more fun. The slide may be flat, or half cylindrical or tubular to prevent falls. Slides are usually constructed of plastic or metal and they have a smooth surface that is either straight or wavy. The user, typically a child, climbs to the top of the slide via a ladder or stairs and sits down on the top of the slide and slides down the chute. In Australia, the playground slide is known as a slide, slippery slide, slipper slide or slippery dip depending on the region. Sliding pond or sliding pon (a corruption of "slide upon") is a term used in the New York City area, whereas sliding board is used in the Philadelphia area and other parts of the Mid-Atlantic. History The earliest known playground slide was erected in the playground of Washington DC's "Neighborhood House ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Friction
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: *Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into ''static friction'' ("stiction") between non-moving surfaces, and ''kinetic friction'' between moving surfaces. With the exception of atomic or molecular friction, dry friction generally arises from the interaction of surface features, known as asperities (see Figure 1). *Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. *Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. *Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body. *Internal friction is the force resisting motion between the elements making up a so ...

Play (activity)
Play is a range of intrinsically motivated activities done for recreational pleasure and enjoyment. Play is commonly associated with children and juvenile-level activities, but may be engaged in at any life stage, and among other higher-functioning animals as well, most notably mammals and birds. Many prominent researchers in the field of psychology, including Melanie Klein, Jean Piaget, William James, Sigmund Freud, Carl Jung and Lev Vygotsky have erroneously viewed play as confined to the human species, believing play was important for human development and using different research methods to prove their theories. Play is often interpreted as frivolous; yet the player can be intently focused on their objective, particularly when play is structured and goal-oriented, as in a game. Accordingly, play can range from relaxed, free-spirited and spontaneous through frivolous to planned or even compulsive. Play is not just a pastime activity; it has the potential to serve as an impo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Swing (seat)
A swing is a seat, often found at playgrounds for children, at a circus for acrobatics, acrobats, or on a porch for relaxing, although they may also be items of indoor furniture, such as the Latin American hammock or the Indian oonjal. The seat of a swing may be suspended from chains or ropes. Once a swing is in motion, it continues to Oscillation, oscillate like a pendulum until external interference or drag brings it to a halt. Swing sets are very popular with children. On playgrounds, several swings are often suspended from a shared metal or wooden frame, known as a swing set, allowing more than one child to play at a time. Such swings come in a variety of sizes and shapes. For infants and toddlers, swings with leg holes support the child in an upright position while a parent or sibling pushes the child to get a swinging motion. Some swing sets include play items other than swings, such as a rope ladder or sliding pole. For older children, swings are sometimes made of a flexi ...

Outdoor Playset
An outdoor playset is a structure erected outside for children to play on and around. Components Typical components of an outdoor playset include: * Towers. In a playset, a tower is a vertical structure with one or more decks placed at various levels. A deck is essentially a horizontal play surface contained within or attached to a tower. * Bridges. Towers may be connected to one another via fixed bridges or chain bridges for children to walk across. * Ladders. Rope ladders and fixed ladders are common accessories for playsets. * Sandboxes. A sandbox often accompanies an outdoor playset. * Slides. Playground slides may be covered or uncovered. * Swings. Swings are usually mounted on a free-standing swing set. * Monkey bars. Towers may be connected by monkey bars as well as bridges. Safety In July 2001, the U.S. Consumer Product Safety Commission (CPSC) reported that each year, more than 200,000 children are taken to hospital emergency rooms due to playground-related injuri ...

Jungle Gym
A jungle gym (called a climbing frame in British English) is a piece of playground equipment made of many pieces of material, such as metal pipes or ropes, on which participants can climb, hang, sit, and—in some configurations—slide. Monkey bars are a part of a jungle gym where a user, hanging in the air, swings between evenly spaced horizontal bars. In Australian English, the term "monkey bars" is sometimes used to refer to the entire jungle gym. History The first jungle gym was invented in 1920 and patented by lawyer Sebastian Hinton in Chicago. It was sold under the trademarked name Junglegym™. Hinton's second prototype "jungle gym" is still standing at Crow Island School in Winnetka, Illinois. The term "monkey bars" appears at least as far back as the 1930s, though Hinton's initial 1920 patent appeals to the "monkey instinct" in claiming the benefits of climbing as exercise and play for children, and his improvement patents later that year refer to monkeys shaking the ...

Traumatic Head Injuries
A head injury is any injury that results in trauma to the skull or brain. The terms ''traumatic brain injury'' and ''head injury'' are often used interchangeably in the medical literature. Because head injuries cover such a broad scope of injuries, there are many causes—including accidents, falls, physical assault, or traffic accidents—that can cause head injuries. The number of new cases is 1.7 million in the United States each year, with about 3% of these incidents leading to death. Adults have head injuries more frequently than any age group resulting from falls, motor vehicle crashes, colliding or being struck by an object, or assaults. Children, however, may experience head injuries from accidental falls or intentional causes (such as being struck or shaken) leading to hospitalization. Acquired brain injury (ABI) is a term used to differentiate brain injuries occurring after birth from injury, from a genetic disorder, or from a congenital disorder. Unlike a broken bon ...

Injury
An injury is any physiological damage to living tissue caused by immediate physical stress. An injury can occur intentionally or unintentionally and may be caused by blunt trauma, penetrating trauma, burning, toxic exposure, asphyxiation, or overexertion. Injuries can occur in any part of the body, and different symptoms are associated with different injuries. Treatment of a major injury is typically carried out by a health professional and varies greatly depending on the nature of the injury. Traffic collisions are the most common cause of accidental injury and injury-related death among humans. Injuries are distinct from chronic conditions, psychological trauma, infections, or medical procedures, though injury can be a contributing factor to any of these. Several major health organizations have established systems for the classification and description of human injuries. Occurrence Injuries may be intentional or unintentional. Intentional injuries may be acts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
