•A spiral is a circular arc with a radius that’s either increasing or decreasing.
•If an object is pulled inward then the spinning motion accelerates by the Coriolis force.
•A helix is circular motion with the center of the circle moving perpendicular to the circle.
•A cycloid is the path of action for a point on the rim of a rolling wheel.
•For motion with a cycle, as in a walk, some paths of action are variations of circular arcs.
