In physics and geometry, the troposkein (from Ancient Greek: τρόπος, romanized: trópos, lit. 'turn' and: σχοῖνος, romanized: skhoînos, lit. 'rope') is the curve an idealized rope assumes when anchored at its ends and spun around its long axis at a constant angular velocity. This shape is similar to the shape assumed by a skipping rope, and is independent of rotational speed in the absence of gravity, but varies with respect to rotational speed in the presence of gravity.
