What is the main reason that the gravitational attraction between Earth and the Moon changes each day?

The gravitational attraction between the Earth and the Moon changes each day because the distance between the Earth and the Moon changes each day. This is because the orbit of the Moon around the Earth is not purely circular - it is elliptical - with an apogee of about 406,000 kilometers, and a perigee of about 363,000 kilometers. Gravitational attraction between two objects is proportional to their masses and inversely proportional to the square of the distance between them.


Does the gravitational force vary with the distance between earth and sun?

The gravitational force between the Earth and sun certainly depends on the distance between the Earth and sun. But the gravitational force between, for example, the Earth and me does not.


Why does the gravitational attraction between earth and the moon changes each day?

The gravitational attraction between the Earth and the Moon does not change significantly on a daily basis. However, the relative positions of the Earth, Moon, and Sun do create variations in the gravitational forces experienced, leading to phenomena like tides.


If the distance between the Earth and the Sun were doubled how would the gravitational?

If the distance between Earth and the Sun were doubled, the gravitational force between them would decrease by a factor of 4 (inverse square law). This means that the gravitational pull on Earth would be weaker, leading to changes in its orbit and potentially impacting its climate and seasons.


If the average distance between Earth and the Sun were doubled what changes could occur in the Suns gravitational pull?

Its pull on the earth would be 25% as strong.


What is the relationship between Earth and gravitational force?

Earth has gravity or gravitational force that attracts the moon to the Earth.


How satellites stay in orbit?

The reason that satellites stay in orbit around Earth is because of two factors. Velocity and the gravitational pull between the satellite and the Earth.


What is the primary reason for tides on Earth?

The gravitational affect of the moon.


Reason for revolution of earth around sun?

The main reason for the revolution of the Earth around the Sun is the gravitational force of the Sun.


Does the gravitational attraction between earth and an asteroid decrease as the asteroid approaches earth?

The gravitational force (or attraction) between any two objects increases as the distance between them decreases. Thus, as an asteroid approaches Earth, the Earth's gravitational pull will increase as it gets nearer.


If a spacecraft travels from earth to the edge of the solar system what will happen to the gravitational pull between earth and the spacecraft?

The gravitational pull between earth and the spacecraft will become insignificant.


How does gravitational force holds the earth together?

Gravitational force is the force of attraction between all objects with mass. On Earth, this force keeps objects, including the Earth itself, held together. It is the reason why all objects are pulled towards the center of the Earth, keeping them from floating off into space.
