- 1. Multiple Choice
What is the Universal law of gravitation equation? (remember, d and R are the same thing)
F = m1⋅m2/d2
G = m1⋅m2/(d)2
F= d2/m1⋅m2
G= d2/m1⋅m2

- 6. Multiple Choice
A moon is located at 1 unit out from the planet it orbits. If that moon was orbiting at 2 units out from the planet, how much would the gravitational force on the moon be compared to its distance at 1 unit? F=m1m2/d2
1/4 as much
1/6 as much
