① This GeoGebra example dynamically demonstrates the vertical displacement of a point on a Ferris wheel as it rotates, visually linking circular motion to its vertical projection. ② Core mathematical concepts include trigonometric functions (sine and cosine), parametric equations of a circle, rotation and angle measurement, and vertical distance calculation. ③ Construction uses commands: Circle, Segment, Rotate, Angle, Line, OrthogonalLine, Intersect, and Distance; key objects include Time (slider), Grd (ground), C (center), c (circle), G1/G2 (reference points), a (radius), α (angle), and multiple Zero' points for tracking positions. ④ Suitable for high school students learning trigonometry, circular motion, and geometric transformations, as well as for physics demonstrations of simple harmonic motion.
