Question

A spaceship orbiting earth flies to the moon. How is the gravitational force pulling on the spaceship related to the distance that the spaceship is from the earth?

A. As the distance from the earth increases, the gravitational pull on the spaceship would decrease.


B. The gravitational pull of the earth is constant and therefore the gravitational pull on would not change.


C. As the distance from the earth decreases, the gravitational pull on the spaceship would decrease.


D. There is no gravity on the moon and therefore only the earth will exert gravitational force on the spaceship.

Answer 1

The correct answer is A

Answer 2

A is Correct, because as you increase the distance between the spaceship and Earth the gravitational force would be less and according to Isaac Newton's Gravitational formula F = (G Mm)/r^2, the distance r is in inverse relationship to the Force.
