What are the example of gravitational force?
One good example are the fact that when you stand up, there is a force ... known as your "weight" ... that holds you down to the floor. That force is nothing but the force of mutual gravitational attraction between you and the earth.
Everything attracted towards the center of earth but gravity is zero at the center of earth.why?
There is nothing special about the center of the Earth itself; the attraction is in that direction, due to the accumulated effect of the attraction from different parts of the Earth. At the center of the Earth itself, the gravitational attraction towards the left, for example, by some pieces of planet Earth, would be exactly compensated by gravitational attraction towards the right, by other pieces of the planet.
Is your sun and other stars far away in another galaxy too far to feel a gravitational force between them?
Galaxies do exert significant gravitational attraction on other galaxies. For example, the Greater and the Lesser Magellanic Clouds are galaxies that orbit our own galaxy, the Milky Way. In that sense, the stars in one galaxy do have a gravitational interaction with those in other galaxies. Of course, the more distant galaxies have correspondingly less gravitational interaction with ours.
Why does the gravitational force between the Earth and moon predominate over electrical forces?
Between the Earth and the Moon, for example, there is no net electrical force. So the weaker gravitational force, which is only attracts, remains as the predominant force between these bodies.
How mass affect the size of the gravitational force between two object?
The force is proportional to each of the masses. For example, if one of the masses is doubled, the gravitational force will also double.
What does increasing distance between objects have on the gravitational attraction between them?
The force of gravitational attraction is inversely proportional to the square of the distance between the centers of mass of the objects. For example, if the distance increases by a factor of two, the attraction is reduced by a factor of four.
What type of bond is contained within an ionic compound?
The bond is an ionic bond, an electrostatic attraction between oppositely charged ions. an example is NaCl which contains sodium ions, Na+, and chloride, Cl-, ions. The sodium chloride lattice is held together by electrostatic attraction between them.

Does a massive elliptical galaxy have a lot or very little gravitational force on other galaxies?
Massive means there is a lot of mass - and gravitational attraction depends on the amount of mass. The amount of gravitational attraction also depends on the distance - i.e., the effect will be less at larger distances. The gravitational attraction between galaxies is strong enough to make galaxies in a galaxy cluster stay together - for example, in our Local Group.
What does gravitational?
It means something pertaining to gravity. For example the gravitational force is the force exerted by gravity. And a gravitational wave is a wave of the gravitational field.n.Physics. The natural phenomenon of attraction between physical objects with mass or energy.The act or process of moving under the influence of this attraction.A movement toward a source of attraction: the gravitation of the middle classes to the suburbs.
Why there is no force of attraction between closer objects?
If you mean gravitational attraction, there is such a force between ANY two objects. The force depends on the distance (if two objects are closer, the attraction is stronger), and on the masses involved (if the masses are larger, the force is larger). The masses of "everyday" objects, for example two people, are so small (for the purposes of the gravitational force) that the force is hard to measure.
What are the force of attraction between particles called?
There is more than one force of attraction. Electrostatic attraction is the action of electric fields. Gravity is another force of attraction And magnetism is yet another force of that can attract. The one we "use" every day is gravity. It is with us from conception to death, and we live our lives in a gravimetric field.
What are square numbers used for?
There are many physical phenomena which depend on squares. For example, the strength of gravitational or magnetic attraction between two bodies is inversely proportional to the square of the distance between them.
What does hydran bond mean?
Do you mean hydrogen bond? This is an electrostatic (mainly) attraction, for example, between the H (slightly positively charged) on one water molecule with the O (slightly negative) on another.
What is the definition of gravitational?
Gravitational is a term used to refer adjectively to gravity, or to the actions associated with or resulting from the force of gravity. A good example is gravitational lensing, which refers to the effect that a massive gravity well has on light originating behind it and moving "around" it to reach an observer.
What does gravitational mean?
force of attraction exerted by the earth
Is an example of an electrostatic force acting in an atom neutron attracting an electron a proton attracting an electron an electron attracting another electron a neutron attracting a proton?
This is valid only for the attraction between a proton and an electron.
