Is Mass the force resulting from the pull of gravity upon an object?

Answer 1

No. Mass is how much substance there is. Gravity is a force. It causes acceleration of a mass in a direction, such as towards the center of the Earth. Weight is due to resistance to acceleration, whether by standing on a fixed surface of the Earth or mounted on the Earth (like a floor of a building), or the floor or seat of a rocket when the rocket is firing. More acceleration or more gravity increases weight, for a given mass.

In space you are weightless when the rocket is turned off - and subject to the pull of the planet , moon or sun nearby and to a lesser extent the rest of the objects in the universe. Even though weightless you still have your full mass.

Note: this definition of weight is not stated this way is physics textbooks. Most authors are repeating the way they learned it. But think about it - the concept is sound. Well.. since they haven't said the answer, i will, it is not mass, but weight. Weight is that force. Mass is how much space is occupied. I could elaborate on this much more but, this is "wikianswers" and people really just want to hear the answer most of time. So it is weight and not mass.

Answer 2

In classical physics, "mass" does not change based on gravity. "Weight", however, is defined as an object's mass multiplied by the acceleration of gravity. So as gravity increases, weight (but not mass) increases.

Answer 3

The force of gravity between two objects is proportional to their masses and inversely proportional to the square of the distance between them.

 

F = G(Mm/R2)

 

Where F is force in newton, G is the universal gravitational constant, 6.674 x 10-11 N m2 kg-2, M and m are the masses of the two objects in kg, and R is the distance between them in m.

Answer 4

The universal law of gravitation is

F= Gm1m2/r2

It means that the more does a body has mass, while the mass of other body may be kept constant or increased, the greater will be the mutual gravitational force between those bodies.
