Explain how the motion of an apple falling to the ground is related to the orbit of the Moon around the Earth. Calculate g for astronauts who orbit the earth 200 km above the surface, given that the mass of the Earth is 5.98×1024 kg and the radius of the Earth is 6.38 x 106 m.  (answer ~9.3 m/s2) Why does a person in free fall experience weightlessness?  Explain. State each of Kepler’s Laws. Given the mass of Mars is 6.4 x 1023 kg…
