Then plug it into this formula F = G(m1m2)/r^2 Where F is the force of attraction G is that constant I spoke about above m1 is your mass m2 is the earth's mass and r is the distance from the center of the earth to your center. You’ll need to know the earth’s mass, the distance between the center of the earth and the center of the object, and the universal gravitational constant. Then plug it into this formula

F = G(m1m2)/r^2

Where F is the force of attraction
G is that constant I spoke about above
m1 is your mass
m2 is the earth’s mass
and r is the distance from the center of the earth to your center.
