According to Aristotle, no motion requires no force. This is because he believed that motion itself is a state of being, not a state of rest, and therefore requires a constant force to maintain it. He argued:

* Natural motion: Objects tend to move towards their natural place, like a rock falling to the ground. This is caused by the object's own nature and does not require an external force. However, the falling motion is still a result of the object's inherent tendency to be in a specific state (at rest on the ground).

* Violent motion: Any motion that goes against an object's natural tendency requires a force to be applied. This could be a push, a pull, or anything that changes the object's state of rest or motion.

Aristotle's ideas were based on everyday observations and lacked the concepts of inertia and friction that are crucial to understanding motion in the modern sense. While he was wrong about motion not requiring force, his ideas were influential for over two millennia and laid the groundwork for later scientific advancements.
