What are the example of gravitational force?
An example of gravitational force is the force that pulls objects toward Earth's surface, keeping us grounded. Another example is the force that keeps planets in orbit around the Sun, maintaining the stability of our solar system.
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.
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.
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.
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.
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 would be the greatest force of gravitational attraction?
The force of gravitational attraction between two objects is strongest when their masses are large and they are very close together. For example, a planet and a star or two massive celestial bodies would experience a strong gravitational attraction between them.
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?
Yes, an example of an electrostatic force acting in an atom is a proton attracting an electron. This attraction occurs due to the opposite charges of the proton (positive) and the electron (negative), leading to the electrostatic force of attraction between them.
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.
Example of non-contact force?
One example of a non-contact force is gravitational force, which acts between objects without direct physical contact between them. This force is responsible for the attraction between all objects with mass in the universe.
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.
Is an example of the electrostatic force acting in an atom?
An example of the electrostatic force acting in an atom is the attraction between the positively charged nucleus and the negatively charged electrons. This force keeps the electrons orbiting around the nucleus in stable energy levels, maintaining the atom's overall neutral charge.
Which is not an example of an electrostatic force that exists within the atom?
The gravitational force is not an example of an electrostatic force that exists within the atom. The electrostatic forces within an atom include the forces between protons and electrons, and the forces holding the nucleus together.
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 kind of force acts through distance?
The gravitational force is an example of a force that acts through distance. It is a force of attraction between two objects that is determined by their masses and the distance between them.
