Can you give me two reasons why a spaceship requires less force to take off from the moon than to take off from the earth?

The force of gravity on the Moon is 1/6th that of the Earth, so a spaceship is pulled down with a smaller force.
The Moon has no atmosphere, so there is no air drag to slow it down.

Is there a point between the moon and the earth where the gravitational force acting on a spaceship is zero?
.
Why can a spaceship move away from Earth?
The force the rocket uses is stronger or equal to the rocket's mass, so it can push it in the opposite direction of the Earth's gravitational pull.
Do the weight of a spaceship changes as it leaves the earth however its mass does not change?
The weight of a spaceship does not change as it leaves the earth, but it does change as it moves from one location to another within the gravitational field of a celestial body such as the earth. The weight of an object is a measure of the force of gravity on that object. It is equal to the mass of the object multiplied by the acceleration due to gravity. The mass of an object, on the other hand, is a measure of the amount of matter it contains and is a constant property of the object. So, while the weight of a spaceship may change as it moves within the gravitational field of a celestial body, its mass remains constant.
What propels a spaceship?
A spaceship is propelled by force. Gas is forced at high speed through the rear of the craft which causes it to be propelled forward.
Why does earth exerts a greater force than the moon?
There are two reasons: The Earth is more massive than the Moon, and the Earth is closer to you than the Moon. If you were standing on the Moon, then the force of gravity due to the Moon would be greater because you are closer to the Moon.

What is the feeling as the spaceship moves out of the gravitational pull nof the earth?
Depends on the net force applied to the people in the spaceship. The gravitational pull of the earth doesn't have a distinct boundary where it stops, but decreases rapidly inversely proportional to the square of the distance.

Why is the force of gravity is not exactly the same everywhere on earths surface?
Two reasons: 1. Different distances from the Earth's center; 2. A "centrifugal force" that counteracts gravity in part.Two reasons: 1. Different distances from the Earth's center; 2.

Can't drop anything without gravity?
Due to the lack of gravity in outer space, an object and the astronauts in a spaceship, will float. Back on Earth, gravity causes an object to drop to the ground, and keeps our feet firmly on the ground.

Gravitational force decreases with distance. What does this mean for a space traveler who leaves earth in a spaceship?
While his ship is accelerating away from the Earth he will feel heavier as acceleration acts a lot like gravity. Upon decelerating he will begin to feel lighter, a lot lighter, until he is almost weightless.
Near the Earth's surface the amount of mass an object has does not affect its acceleration due to gravity?
That is correct. Earth's gravity, often expressed as 9.8 meters per second square, can also be expressed as the equivalent 9.8 Newton per meter. That is, an object of twice the mass will feel twice the force of attraction from Earth. However, it will also have twice the inertia - it requires twice the force to give it a certain acceleration.
