The force of
Earth's gravity is the result of the planets mass and density – 5.97237 × 1024
kg (1.31668×1025 lbs) and 5.514 g/cm3, respectively.
This results
in Earth having a gravitational strength of 9.8 m/s² close to the surface (also known as 1 g), which naturally
decreases the farther away one is from the surface.
