👉 In physics and mathematics, a "corotator" is a mathematical object that has both rotational symmetry and translational symmetry. A "rotor" is an object whose shape is symmetrical around its axis of rotation. For example, a rotor can be a disk or a sphere. The term "corotates" refers to objects that have both rotational symmetry and translational symmetry at the same time. In other words, they have both a non-zero angular velocity along their axes, which means
