Study Notes
Gravitational Variation with Height
- Gravitational acceleration (g) can be calculated at a height (h) using a specific equation (equation 4, not shown here).
Gravitational Variation with Depth
- Gravity's relationship with depth is depicted in a diagram (not shown here) showing Earth as a circle with center O and radius R.
- The diagram illustrates the gravitational acceleration (g) at a point at a depth (R-d) from the center where d is the depth from the surface.
- The angle or radius at a specific depth is represented by Φ.
