Question

collect information about gravity at different locations like mountains in stations and country​

Answer 1

Gravity at different locations:

• The gravitational force is a attractive magnetic force from the core of the earth.
• The acceleration due to gravity at the surface of the earth is 9.8 m/s² which is denoted by the alphabet 'g'.
• The acceleration due to gravity at certain height is given by the formula:

g' = g (1 - 2h/R)

Where,

h = Height; and R = Radius of the earth

• Now, when the height increases g' < g whereas when height is below the surface of the earth g' > g.
• Some of the places in earth have zero gravity due to some mysterious reasons, the places are Santa Cruz California and Michigan.
