Aspacecraft is flying away from the moon toward the earth. the moons gravitational pull on the spacecraft

a. repel the spacecraft

b. decrease

c. increase

d. remain the same

B. Decrease

Explanation: When an spacecraft is flying away from the moon, the moons gravitational pull on the spacecraft will decrease because gravitational force is directly proportional to the mass of the moon and mass of the spacecraft while inversely proportional to the square of the distance between them. So as the spacecraft moves away from the moon, gravitational pull will decrease.
