ns Gravity Review Question 6 O O O Question 8 of 39 If you drop a feather and a steel hammer at the same moment, they should hit the ground at the same instant. Why doesn't this work on Earth, and why does it work on the Moon? a. Air resistance slows the feather on Earth and the magnetic field accelerates the hammer on Earth. Because of that, they land at different times. The Moon doesn't have an atmosphere or a magnetic field. b. Air resistance slows the feather on Earth but doesn't affect the hammer very much. Thus, they land at a different time. On the Moon, there is no air (and no air resistance). c. The magnetic field of Earth affects the steel hammer and increases its acceleration. Because of that, the hammer falls faster than the feather. The Moon doesn't have a magnetic field. d. The feather has an airfoil creating lift in Earth's atmosphere, which slows the feather's fall. Because of that the hammer falls faster. A bird's feather doesn't create lift in the Moon's atmosphere.
