SUMMARY

The maximum gravity experienced by an object approaching a planet occurs at the core/mantle boundary, particularly for Earth. As an object nears the center of the planet, it experiences a net zero gravity field. The determination of the maximum gravity point relies on the planet's composition and can be modeled using Earth's density versus depth, applying Gauss' law for analytical solutions.

PREREQUISITES
  • Understanding of gravitational forces and their behavior near massive bodies.
  • Familiarity with Earth's internal structure, specifically the core and mantle.
  • Knowledge of Gauss' law and its applications in gravitational fields.
  • Basic principles of density and how it varies with depth in planetary bodies.
NEXT STEPS
  • Research the application of Gauss' law in gravitational field analysis.
  • Study Earth's density profile and its implications on gravitational forces.
  • Explore the effects of planetary composition on gravity distribution.
  • Investigate other celestial bodies and their gravity maximum points using similar models.
USEFUL FOR

Students of physics, geophysicists, and anyone interested in planetary science and gravitational studies.

An object approaching Earth (or any planet) experiences increasing gravity as it gets nearer.
However, If the object could continue until reaching the center it would find itself again in a net zero gravity field.
At what point will it experience the maximum amount of gravity?

One way to get the answer would be to model the Earth's density versus depth analytically and use an equivalent form of Gauss' law.
