The swing ride or chair swing ride is an amusement ride that is a variation on the carousel in which the seats are suspended from the rotating top of the carousel. On some versions, particularly on the Wave Swingers, the rotating top of the carousel also tilts for additional variations of motion.

Rotation or rotational motion is the circular movement of an object around a central line, known as axis of rotation. A plane figure can rotate in either a clockwise or counterclockwise sense around a perpendicular axis intersecting anywhere inside or outside the figure at a center of rotation. A solid figure has an infinite number of possible axes and angles of rotation, including chaotic rotation, in contrast to rotation around a fixed axis.
