Question

A body weighs 1000 lbf when exposed to a standard earth gravity g=32.174 ft/s^2,find the mass in kg

Answer 1

Answer:

Hello your answer is here:-

Gravity is not constant around the earth - it varies because the concentration of mass around the earth varies. In fact, mass concentrations (mascons) are used to determine where geological features like meteor craters are. Gravity measurement is part of the subject called Geodesy.

There is an excellent gravity map of the earth shown in Reference.

The information on the variation of the earth's gravity is also important determining satellite orbits and ballistic missile trajectories.
