The leading theory is that after the earth formed a mars sized object collided with the earth bonding the two and ejecting material into the orbit of the new larger earth, this material coalesced to form the moon.
Yes, according to the prevailing theory. The idea is that the early Earth was struck a glancing blow by another protoplanet about the size of Mars. Much of the Earth's crust was peeled away and put into orbit about the now-enlarged Earth. Over a surprisingly short time span, the orbiting material coalesced to form the Moon.
This model has the nice feature of explaining the much lower density of the Moon. Before the big collision, the iron, nickel, and other heavy elements in the early Earth sank to the center (giving the Earth its current nickel-iron core). The collision created the Moon from the crustal material of Earth, which was relatively depleted in those heavy elements because they'd already sunk into the Earth.
One theory about the formation of the moon is that a big body moving through space hit the earth and tore some of it off, then went into orbit about our planet. If you think about it, there aren't many logical ways to explain how a body as large as our moon could be captured by earth. The moon probably could not have formed at the same time as earth because there is too much of it too close. It is most unlikely to have appeared in a local accretion disk. Lastly, the few moon rocks that were brought back suggest that what is there is like what is here. If that's the case, what is there now must have been here at one time.
Current measurements show that the earth is slowing and the moon is spiraling out to higher and slower orbit. Therefore, in the past, the days and months were shorter and the moon was closer. If we extrapolate back about 4.1 to 4.5 billion years ago the moon was ludicrously close and the earth was dizzy fast. But what are the projected numbers?
A mars-sized object hit the earth and the piece that broke off became the moon
The Earth and the moon form a system together. Solar eclipse is an event in which the moon passes between the Earth and the Sun and the moon's shadow falls on Earth.
The Moon is a satelite of the Earth and the Earth is the 3rd planet out form the Sun in the solar system.
The vapor form, the liquid form, and the solid form are.
is like nothing
It did not get pulled in by Earth's gravity. The moon most likely formed when a small planet collided with Earth early in its history, producing a ring of debris around Earth which coalesced to form the moon.

Reflected sunlight, for sure, travels from the Earth to the Moon. Reflected sunlight from the Moon also travels to Earth. That is why we can see the Moon.
No, it is the gravitational attraction of the moon.
The phases of the moon are the result of the ever-changing positions of the Earth, moon, and sun relative to one another. When the moon and the sun are on opposite sides of the earth (whereby the sun, earth, and moon form a straight line), a full moon occurs. When the moon and sun are on the same side of the earth (whereby the sun,moon, and earth form a straight line), a new moon occurs.
There is no math to "show". The moon's distance from earth varies, but the average distance of the moon form earth is about 236,000 miles (378,000 Kilometers).

Sun-Moon-Earth form a right triangle in this case.
The moon is 384,400 kilometers away.
No, they did not form at the same time because the Moon formed after the Earth. The most likely theory is that shortly after the Earth formed 4.5 billion years ago, a giant object (about the size of Mars) collided with the Earth. Large amounts of debris were thrown into space which began orbiting earth and eventually came together to form the moon.
