sometimes, gravity just takes hold and pulls anything that has mass and occupies space towards the ground — solid concrete or soft soil or grassy meadows or murky waters or wherever depending on where you are.
but then again, if it’s not the concrete, it’s towards another object, and that force of gravitation between you two is proportional to the mass of the pullee times the mass of the puller and inversely proportional to the square of the distance between the elements involved — BUT, in this case, though, newton’s theory of universal gravitation was proven false, no amount of distance lessened the F.
so, i’m really sorry.
there was nothing i could do. you can’t fight gravity. no one could.

Boy and girl
If a 50 kg (110 lb) girl sat 0.5 m (19.7 in) from a boy who was 75 kg (165 lb), what would be the gravitational attraction between them?
Substituting the values into the equation, you get:
F = GMm/R² = (6.67*10-11 N-m²/kg²)(50 kg)(75 kg)/(0.5 m)(0.5 m) = 10-6 N or one-millionth of a Newton
That is a very small gravitational attraction, but it can be measured on a sensitive instrument.
Effect of Moon on person
The gravitational pull from the Moon on the 50 kg (110 pound) girl is:
F = GMm/R² = (6.67*10-11 N-m²/kg²)(50 kg)(7.35*1022 kg)/(3.84*108 m)² = 1.67*10-3 N = 0.00167 N
She would not notice the pull from the Moon, since the gravitation pull on her toward the Earth is 490 N. But still, she is attracted more toward the moon than the boy who was sitting next to her.
