Wippe

Wippe is the German term for a seesaw, a playground apparatus consisting of a long beam balanced on a central pivot, with seats or handles at either end. It is a classic example of a lever and is commonly found in parks, schoolyards, and playground areas.

How it works: Two users sit on opposite ends of the beam. When one side is weighed down, the other rises, and the motion continues as users shift their weight. The device operates as a class I lever, with the fulcrum at the center between the input force (a person’s weight) and the output motion of the beam. Balanced weights keep the seesaw level.

Design and safety: Modern Wippen are built from durable materials such as steel or treated wood and include features like non-slip surfaces, sturdy grips, and protective edging. Ground safety is addressed with impact-absorbing surfacing, such as rubber tiles or mulch, to reduce injury risk from falls. Compliance with local playground standards and routine maintenance are typical requirements to ensure stability, smooth pivoting, and safe operation.

Etymology and usage: The term Wippe is standard in German to describe a seesaw used for recreation and play. Seesaws are widely recognized as simple machines that illustrate balance and rotational motion, serving both educational and entertainment purposes in outdoor environments. Variants exist, including larger or spring-loaded versions, but the basic concept remains a lever balanced on a central pivot.
