This example demonstrates the variation of gravitational acceleration below the Earth's surface. Key mathematical concepts include the formula for gravitational acceleration and the Earth's radius. Using GeoGebra commands such as Circle, Vector, and Intersect, the pattern of gravitational acceleration with depth is visually illustrated. Suitable for high school physics and mathematics courses.

GeoGebra Commands & Parameters

  1. Circle(G, r) → h
  2. Circle(G, ((1 - d) * r)) → k
  3. OrthogonalLine(G, xAxis) → i
  4. Intersect(k, i) → H, I
  5. Intersect(h, i) → J, K
  6. Vector(K, I) → v
  7. Point(v) → L
  8. Point(h) → A
  9. Vector(G, A) → u
