This example demonstrates how the gravitational acceleration changes with depth 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, OrthogonalLine, and Intersect, the Earth model is constructed and the curve of gravitational acceleration with depth is displayed. 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
