Blast from the Past

•        What are the two major factors that determine the gravitational attraction between two objects?

•        What are the two major objects in the solar system that are responsible for the Earth’s tides?

•        Which object of those two objects is the most responsible for the Earth’s tides?

•        True or False - The moon causes a gravitational pull on one part of the Earth that is stronger than the other part of the Earth.

•        What causes the water on the Earth to bulge out on the part of the Earth that is on the side not facing the moon?

•        Why can we as humans jump about 6 times higher on the moon than on Earth?  Be as specific as possible when answering this question.

n      If a planet is traveling at a speed that is slower than its critical speed, what would eventually happen to the planet?  Why?

n      If the Earth had two moons that were at 90 degree angles from one another, what would happen to the ocean levels on different parts of the Earth?

n      The facts:

                        The Earth spins around its axis once in 24 hours.

                        The Moon takes about 27.322 days to go around the Earth.

n      Why on most places on Earth are there about two high tides and two low tides in one day?

n      Draw a picture of the Sun and the moon at a 90 degree angle to the Earth.  Show the two places where there is a small high tide and the two places where there is a small low tide.  Explain in detail why there is a small high tide and small low tide in those places.  Each place has a slightly different reasoning.
