    Aristotle's Wheel Paradox When you roll a rigid wheel over a distance equal to its circumference you seem to find that the circumferences of the inner (blue) and outer (red) circles are equal. 🤔 Can you guess the fallacy?pic.twitter.com/afuaSFRcUg

        the horizontal (x) component of motion is the distance traveled by the center of the circle. The actual path of points on the circumference is defined by the cycloid diagram below:pic.twitter.com/3U5fxg3Vtr

        The inner circle runs faster (?)

        They rotate at the same angular velocity. But the inner circle "slips" too, while the outer one does not.

        The two points take different paths, travelling different distances. The fact that the horizontal distance they move is equal doesn't factor in the fact that the point further out takes a longer path.

        Also, the distance that the inner point moves horizontally isn't related to *its* circumference. It's just a point on a larger wheel being carried a distance related to *that* wheel's circumference. Its movement through space is unrelated to its own dimensions.

        The angular velocity of the inner circle should be greater than that of the outer circle. Where's my prize ????
