Question
The Moon's mass is 7.34 x 10^22 kg, and it is 3.8 x 10^8 away from Earth. Earth's mass if 5.97 x 10^24 kg.
a. Calculate the gravitional force of attraction between Earth and the Moon.
b. Find Earth's gravitional field at the moon.
GIVEN:
Moon's mass = 7.34 x 10^22 kg
Earth's mass = 5.97 x 10^24 kg
Would you use g = Fg/m?

Answers
a) F = G m M/R^2
b) g = G M/R^2
m = Moon's mass = 7.34 x 10^22 kg
M = Earth's mass = 5.97 x 10^24 kg
R = 3.8 x 10^8 m
G = universal constant of gravity
b) g = G M/R^2
m = Moon's mass = 7.34 x 10^22 kg
M = Earth's mass = 5.97 x 10^24 kg
R = 3.8 x 10^8 m
G = universal constant of gravity
