Playground slide

A playground slide is a sloped structure with a smooth surface that lets children descend from an elevated platform to the ground by sliding.

Gravity: Gravity is the attraction between masses, described in modern physics as the curvature of spacetime. It accelerates a child down the slide’s slope.
Playground equipment: Playground equipment comprises structures and devices designed for recreation in play areas. Slides are one type of equipment within this broader group.
Playground: A playground is an outdoor or indoor area designed for children's play and recreation. Slides are common fixtures in playgrounds.
Playground safety: Playground safety comprises practices and design measures that reduce hazards in play environments. Slide design, maintenance, and use all affect playground injury risk.
Friction: Friction is resistance to relative motion between surfaces in contact. It slows sliding and depends on the surfaces and clothing involved.
Platform (structure): A platform is a raised, level surface that supports people or objects. It provides the elevated starting point for a slide.
Tube slide: A tube slide is an enclosed slide formed as a curved or straight tunnel. Its enclosure changes the descent by limiting visibility and exposure.
Consumer Product Safety Commission: The Consumer Product Safety Commission is a United States federal agency that regulates consumer product safety. Its playground guidance addresses slide design, use zones, and fall hazards.
Inclined plane: An inclined plane is a flat surface set at an angle, used to raise or lower objects with less force. A slide is a play-oriented form of this simple machine.
Staircase: A staircase is a set of steps connecting different levels of a building or structure. Stairs commonly provide access to a slide’s elevated platform.
