(geometry) The locus of a point on the circumference of a circle that rolls without slipping on a fixed straight line.
Balls rolling under uniform gravity without friction on a cycloid (black) and straight lines with various gradients. It demonstrates that the ball on the curve always beats the balls travelling in a straight line path to the intersection point of the curve and each straight line.
