Why does a wheel-o stop is space?

A wheel-o stops in space due to the absence of external forces acting on it. In a vacuum, once an object is set in motion, it will continue to move indefinitely unless a force, such as friction or gravity, acts upon it. If the wheel-o encounters resistance from a surface or an obstacle, it will eventually come to a stop. Additionally, any internal mechanisms or energy loss can also contribute to its cessation of motion.
