You are an astronomer on board a space craft headed to a new Earth (Earth A1) and its Moon, in another part of the galaxy. Calculate, using Newton's LUG
formula, the gravitational force between Earth A1 and its Moon. The mass of the
Earth A1 is 6.25 x 10^24 kg and the mass of the moon is 7.00 x 10^21 kg. The
distance between Earth A1 and its Moon is 3.8 X 10^6 km.
1. What are the Units of Force?
2. What is the product (2 masses multiplied) of the 2 masses? (Earth A1 and it's Moon)
3. What is the Force using Newton's LUG formula? (round to the nearest tenth and put your
answer in Scientific Notation)
4. What would result, in terms of the Force, if the Moon suddenly moved twice as far from
Earth A1, but still kept its same mass?
