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. Whereas sliding board is used in the Philadelphia area and other parts of the Mid-Atlantic.
