How does gravity change with location?

Answer 1

Take a simple bar magnet for example. Place an iron-like object near it and its attracted instantly. Place the object farther away and the object is influenced by less of the magnet's magnetic field. Similarly, the planet Earth, is a huge magnet. The magnetic field thus produced by the earth has an attraction of objects toward its center, i.e. gravity. The farther away from center of Earth you get(or the farther away from a magnet you put a metal object) the less attracted you or I become. So the higher in altitude from the surface of the Earth, the less of an effect gravity will have. Note that this change in gravitational effect is not a linear change, but logarithmic. In order to fully escape Earth's gravity, one would have to travel beyond Earth's Moon.

Answer 2

Gravity varies based on factors such as altitude, latitude, and the density of Earth's crust. Generally, higher altitudes have slightly weaker gravity due to the greater distance from Earth's center, while gravity is slightly stronger at the poles compared to the equator due to the shape of the Earth. However, these variations are very small and usually not noticeable in everyday life.
