Why can a spaceship move away from Earth?
A spaceship can move away from Earth due to the principle of inertia, which allows objects in motion to stay in motion unless acted upon by an external force. By firing its engines in the opposite direction of Earth, the spaceship can generate thrust that propels it away from the planet.
Do you weigh less on Earth than in a spaceship orbiting 800 km above Earth?
No, you actually weigh slightly less in a spaceship orbiting 800 km above Earth compared to your weight on the surface of Earth. This is because weight is the force of gravity acting on an object, and gravitational force decreases with distance from the Earth's center. In orbit, you experience microgravity, which gives the sensation of weightlessness, but your mass remains the same. Thus, while you still have weight in a spaceship, it is less than what it would be on Earth's surface.
Why does a spaceship orbit around earth?
Because it has reached the "Orbit" zone in the upper atmosphere where the gravity is only strong enough to keep it from floating off into space, but not strong enough to pull it down back to Earth. Thus why it just travels parallel to the Earth's surface
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.
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 is the difference of density on earth compared to a spaceship?
The density on Earth is higher than in a spaceship, as the spaceship is typically designed to be lightweight. On Earth, the atmosphere and gravitational force contribute to a denser environment, whereas a spaceship is constructed to be less dense for efficient travel in space.

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.

How does a spaceship fly in space?
A spaceship flies in space by using thrusters to generate propulsion. By expelling mass in one direction, the spaceship experiences a reaction force in the opposite direction, allowing it to move forward. In space, there is no air resistance to slow the spaceship down, so it can continue moving at a constant speed until another force, like gravity or another thruster, acts upon it.
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.
What is the main factor in determining the amount of thrust a rocket requires to leave the Earth's atmosphere?
Payload weight.
How do rockets propel a spaceship forward?
Rockets propel a spaceship forward by expelling high-speed exhaust gases in the opposite direction to create a reactionary force as per Newton's Third Law of Motion. This force pushes the rocket and the spaceship it is attached to in the opposite direction, propelling them forward through space.
