All masses have a gravitational pull which increases with the size of the mass - if you took a marble though, it would have a gravitational pull but it is too weak to be noticeable. Two mases attract eac other because of their gravitational pull.

How is occur gravitation?
Gravity is an effect of mass. Two masses will attract each other proportional to their masses and the force varies by the inverse square of the distance.
What are the two properties of the pull of gravity?
-- It always attracts, never repels. -- The gravitational force is always equal on both of the masses that attract each other.
Which force varies according to the masses of two objects and the distance between them?
The equal pair of mutual gravitational forces that attract the objects toward each other.
What force that gravity exerts on an object is called?
The mutual force with which every two masses attract each other because of gravity is referred to as the "weight" of the objects.
How earths gravity pulls a rock?
The earth and the rock both pull each other, with equal force, because of the way gravity works. We don't really know how, but we do know that any two masses always attract each other with equal forces that depend on the product of the two masses and the distance between them.
What is the law of universal law of gravitation?
the principle that two particles attract each other with forces directly proportional to the product of their masses divided by the square of the distance between them
When two opposite electrical forces are near each other what will happens?
they will attract
When two objects have the same charges they attract each other?
They do not. Rather, objects with opposite charges attract each other.
What w is the amount of force with which gravity is pulling down on something?
"Weight" is the size of each of the equal forces with which two masses, such as the Earth and an elephant, or the Earth and a person, attract each other because of gravity.
Amount of force gravity exerts on an object?
The strength of the mutual forces of gravity that attract two objects toward each other is called the "weight" of each object in the presence of the other one. The strength of the mutual gravitational forces that attract you and the earth toward each other is called your weight on the earth. Nobody cares about the earth's weight on you, but it's exactly the same number.
Would 2 protons attract or repel each other?
"Opposites attract". So two electrons repel each other.
What do objects with unlike charges do?
When unlike charges are brought together they attract eachother.
