Which of these is caused by the moon's gravitational pull?

Answer 1

Earth is more dense than the moon because the earth has an iron-rich core, where the moon does not. The moon was formed eons ago when Earth was struck by a planetesimal. The result was that some of the Earth's crust and mantle was sent orbiting in space, forming the moon. However, the core of the Earth, the part full of iron, did got get sent into orbit. This explains why the Earth is more dense than the moon.

Answer 2

The force of gravity (simple theory) is equal to the product of the masses of the two objects and the square of the distance between them, times the gravitation constant of the universe. The Earth pulls on the moon, enough to pull it towards Earth, but no enough to make it fall. The force is only enough to keep it falling, but moving around at a speed that is countered by the curvature of the Earth. It is also pulling on us, which causes tides. Gravity is the natural force that brings masses together. It is relatively weak when compared to other forces, but it adds up with larger masses.

Answer 3

No, the moon's gravitational pull is much weaker than the Earth's because it is smaller, so therefore has a stronger pull. The heavier an object's mass is in space or any other planet, the stronger the gravitational pull.

Answer 4

The Moon's gravitational pull is stronger than the Sun's. Yes, the Sun is far more massive than the Moon - but it is also much farther away. Gravitational attraction increases by the mass, but decreases by the SQUARE of the distance.

Answer 5

Earth has more mass. Gravity is proportional to mass.

Earth has more mass. Gravity is proportional to mass.

Earth has more mass. Gravity is proportional to mass.

Earth has more mass. Gravity is proportional to mass.

Answer 6

The earth has substantially more mass than the moon. As a result, the earth has a stronger gravitational field than the moon does.

At an equal distance from the center of each body, say 20,000 miles or 50,000 miles, the moon's gravitational pull will be substantially less than the earth's.

On the other hand, if you get close enough to the smaller body, its pull can exceed the pull from a larger body that is much further away.
The moon's gravity is weaker than that of the earth. Gravity is a function of mass; the more mass something has, the more gravity it has. The earth is larger and more massive than the moon, so it has more gravity than the moon.

Answer 7

because inside the earth gravitational force cancel each other; according to the following reasoning: * the cause of gravity is mass. * the gravity is a force. * force is a vector quantity. * if to equal and opposite forces are exerted on the same object they cancel each other. * in the core of the earth the net gravity= 0. since the gravitational forces from each atom in earth will cancel eachother. * thus the gravity measured inside the earth is not correct, it will be normally less than the right measurment.

Answer 8

The earth makes gravity because if there was no gravity then every one would be floating around in the air and then there would be no actual point in there being a earth in the first place.

As far as how gravity works, physicists are still working on it. According to Einstein Earth makes a kind of depression in fabric of space-time, cause gravity around Earth. Many scientists believe that gravity is caused by the interchange of particles called gravitons, and that another particle, the Higgs boson, creates a filed called the Higgs field, which is what allows gravitons to be exchange between objects, creating a gravitational pull.

Answer 9

On the surface of the Earth, the gravitational attraction of any object towards the center of the Earth is about six times greater than the gravitational force of the same object on the surface of the Moon towards the center of the Moon.

There are two factors that explain why this is true. The gravitational force on the surface of a round object is inversely proportional to the square of distance to the center of the object. The influence of the radius of the Earth is then to decrease the gravitational force it exerts at its surface.

The gravitational force at the surface of a round object is proportional to the mass of the object. The larger mass of the Earth then tends to give it a greater gravitational force at its surface.

Two competing effects can be resolved using the ration of the formula for caculating gravitational force which, using the above, is a simple fraction.

The Earth is about 81 times the mass of the moon.

The Earth's radius is about 3.66 times larger than the radius of the moon.

Earth gravity is 81/(3.66*3.66)=6 times greater than the Moon.
Because the gravitational force is stronger on the Earth than on the moon.

Answer 10

The phases of the moon are caused by the moons position relative to the earth and sun. The tides are influenced also, but not entirely caused by the moons position relative to the earth and sun.
