How do we think Earth’s Moon formed?
A. The Moon was spun away from Earth shortly after Earth formed.
B. The Moon and the Earth formed at the same time from the same material.
C. The Moon was captured as it passed near Earth.
D. The Moon resulted from the impact of a Mars sized object with Earth. Much of the ejected material formed the Moon.

13. The Impact Theory: A Mars sized object hit the molten earth after the iron core of Earth was formed. The glancing blow ejected material from the Earths' crust/mantle. Look at the crustal composition of the earth and the moon again. Think about what elements each layer of the earth contains. Think about the density of the Earth and Moon. Why is the moon less dense? Argue why this is how the moon was formed.

6. In studying the Moon and the Earth, we saw that the tidal forces are causing the Moon to be pushed away from the Earth. In our solar system, we have another curious case. Triton, the main moon of Neptune, is in a retrograde orbit, which means it is orbiting in the opposite direction that Neptune is rotating. It is likely a captured object. Because of tidal forces and this odd orbit, Triton is slowly spiraling in toward Neptune. This...

2) Planet Velocities and Energy (10 pts) We talked about how planet formation involves the collisions of bodies (planetesimals, embryos) leading to the growth (and heating) of a planet. Let's think about the velocities and energies involved here. a) The speed of a body in its orbit around the Sun is given by the equation V2= GM.[(2/r) - (1/a)] Here Vis the speed of the body in m/s, G is the gravitational constant, M. is the mass of the Sun...

1. All the planets orbit the Sun in the same direction. This is strong evidence that: Group of answer choices None of these is correct. We do not have any idea yet why the planets are orbiting in the same direction. the solar system resulted from the collision of two medium-sized stars. after the planets formed, collisions between them eventually caused them all to move in the same direction. the planets were formed elsewhere in the galaxy and were later...

Mars is a long way away—33.9 million miles to be exact—from Earth. But, that hasn’t stopped NASA from gaining approval in the bipartisan NASA Authorization Act of 2010 to send humans to Mars in the 2030s. While there are amazing technological and physical challenges associated with such an audacious goal, there are also serious organizational behavior challenges in terms of managing emotions and stress during the six- to nine-month-long journey there and back. Astronaut Scott Kelly, who spent one year...

4. Matlab Solvers: A Case Study in Mechanics Suppose we have two objects orbiting in space, with masses 1 - and , rotating around each other. For example, think of the earth and the moon, where the moon moves around the earth at distance 1. (Of course, here both the masses and the distance are normalized.) A third object, which is relatively much smaller and does not affect the motion of the first two, is also orbiting in space. Think...
