| + | - Origin of Earth-Moon system | ||
| + | - There are three main theories that explain how the Earth-Moon system originated: | ||
| + | - Early in the life of the Solar System as the planets were just beginning to form, the Earth and Moon could have formed together in a process known as accretion | ||
| + | - At some point in the history of the Earth, the moon could have originated elsewhere and it was captured by the gravity of the Earth. In order for this to have occured, the moon would have had to slow down to less than escape speed (Part 2 Problem 1eIC) | ||
| + | - By far the most popular theory, sometime long ago, a Mars-sized object (commonly called Theia) collided with the Earth, ejecting a large amount of material from Earth. This material then accreted to form what is now the Moon. This accounts for the axial tilt of the Earth. | ||
| + | - Satellite-Earth orbit | ||
| + | - The satellite is always falling towards the Earth; however, so long as it is travelling fast enough, the satellite essentially moves out of the way of the Earth as fast as it is falling. Basically, the effects of the satellite's velocity and the gravitational force from the Earth are balanced. | ||
