Is the rotation of a wheel considered translation or rotation?

[Leo]

Wheel rotation is a rotational phenomenon. Here are the relevant explanations: 1. Concept of rotation: In a plane, when a figure is turned around a fixed point in a certain direction by an angle, such movement is called rotation of the figure. This fixed point is called the center of rotation, and the angle of turning is called the angle of rotation. 2. Concept of translation: Translation refers to moving a figure in a certain direction by a certain distance within a plane. Such movement of a figure is called translation, which does not change the shape or size of the object; after translation, corresponding line segments are parallel (or collinear) and equal in length, corresponding angles are equal, and the line segments connecting corresponding points are parallel and equal in length; translation does not alter the shape, size, or orientation of the figure.
