The mass of the object exerting the gravitational pull, and the distance between the two objects. Gravity is all over, but it's effect varies greatly with distance. The girl next to you in Science class is actually exerting a greater gravitational pull on your mass than the Sun, despite their obvious differences in size.
The concentration of the substances that react is one. The temperature is another.
centripetal acceleration counters the acceleration due to gravity creating an equilibrium. the EXACT same way water wont fall out of the bucket if you spin it fast enough. Gravity is also a field and decays as the distance between the two objects increases. GMm/r^2
1). the product of both their masses 2). the distance between the centers of both objects
I think what you're trying to get at is "How big does an object have to be to have gravity?" which is different from "gravitation". Gravitation is something that everything has, big or small. It is the attraction that all objects exert on one another. Gravity, on the other hand, is specifically the force that a massive object exerts on other objects.
Expiration depends on (1) the recoil of elastic fibers stretched during inspiration and (2) the inward pull of surface tension from the film of alveolar fluid.
Distance And Weight (or mass)
Mass and distance.
Mass & distance.
Their masses and the distance apart
The mass of the planet, and the distance from the center of gravity. Gravitational pull is a relation between the mass of two bodies and their distance apart.
The pull of gravity is affected by the amount of mass, and by the distance.
-- The product of the two masses being attracted to each other. (NOT the mass of either one of them individually). -- The distance between their centers of mass.
The two factors related to gravitational pull are (total) mass and distance.
The forces of gravity always pull two objects toward each other.
mass and gravity
The closer the distance, the greater the pull of gravity between them.
Gravity is the attraction between two or more bodies. It is propotional to their mass and inversely proportional to their distance.
