How can we create a gravity

 

Gravity is the gravitational force experienced by a given mass in presence of another

huge mass like mass of planet, mass of moon, mass of sun etc.

This gravitational force is expressed as F = (G×M×m)/R² ,

 

where G is universal gravitational constant, m is the given mass that experience gravitational force

in presence of huge Mass M and R is the distance between masses.

 

Gravitational force experienced by unit mass (acceleration due to gravity)

on surface of huge masses like earth, moon and sun are given below

 

For Earth :-  Mass = 6×10²⁴ kg ,   Radius = 6371 km,  acceleration due to gravity on earth's surface = 9.8 m/s²

For Moon :-  Mass = 7.3×10²² kg, Radius = 1740 km,  acceleration due to gravity on moon's surface = 1.6 m/s²

For Sun :- Mass = 2×10³⁰ kg, Radius = 7×10⁵ km,  acceleration due to gravity on moon's surface = 271 m/s²

 

In nutshell, to create gravity, you need a huge mass like mass of earth, mass of moon, mass of sun etc.

Nearby this huge mass you feel gravity
