This applet demonstrates SHM motion (mass on an elastic string) using a unit circle. Key math concepts include trigonometry and equations. GeoGebra commands used include Circle, Point, Rotate, Angle, Ray, Polygon, Segment. Suitable for high school physics and math education.

GeoGebra Commands & Parameters

  1. Circle(A, 1) → c
  2. Point(c) → C
  3. Rotate(C, ang, H) → P
  4. Angle(C, H, P) → ωt
  5. Ray(Y', B) → b
  6. Circle(Y', 0.2) → d
  7. Polygon(D, E, 4) → poly1, e, f, g, h, F, G
  8. Segment(H, P) → i
  9. Segment(I, J) → j
