Final answer:
A cycloid is the path traced by a point on a circle's circumference rolling along a straight line, crucial in mathematics and physics.
Explanation:
A cycloid is the path traced by a point on the circumference of a circle as it rolls along a straight line, creating a specific curve. The motion of a point on the rim of a rolling wheel can form this shape.
