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?

  • physics - ,

    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
