The force between a planet and a spacecraft is 1 million newtons.What will the force be if the spacecraft moves to half its original distance from the planet?

The force is inversely proportional to the square of the distance. So, half the distance means four times the force.
So, the answer is: 4 million newtons.
additional note: This is true only if the distance referred to is the distance to the center of the planet or if the distance to the planet is great enough to make the radius of the planet insignificant.

How long does it generally take to reach moon from the earth?
It takes about 3 days for a spacecraft to reach the moon. During that time a spacecraft travels about 240,000 miles (386,400 kilometers) which is the distance between Earth and the moon.

What are the difference between a spacecraft and spaceship?
The differenc between a spacecraft and spaceship are none. There isn't any difference between a spacecraft and spaceship.
Find the change in the force of gravity between two planets when the distance between them is increased by a factor of five?
When the distance between the centers of two planets decreases to 1/10th of the original distance,the gravitational force between them increases to 100 times the original force.
If a spacecraft travels from earth to the edge of the solar system what will happen to the gravitational pull between earth and the spacecraft?
The gravitational pull between earth and the spacecraft will become insignificant.
How does the force of gravity between two bodies change when the distance between them is increased by 4?
Provided neither mass changes, the mutual gravitational force of attraction betweentwo bodies decreases to 1/16 of its original value when the distance between theircenters increases to 4 times the original distance.
The force of a gravitation between two objects is 500 newtonswhat would the force of gravitation be if the distance between these two objects increased by 10 times?
when the distence between the two objects is increased by ten times then the force of gravitation will reduce by 100 times.

What is the distance between planet earth and planet Kepler?
There is no planet Kepler. Designations such as Kepler-69c are given to planets discovered by the Kepler spacecraft. This spacecraft has discovered planets ranging from 100 to 7,000 light years away.

How does the distance between two objects affect the strength of gravity?
The mutual force of gravitational attraction between two objects is inversely proportionalto the square of the distance between their centers of mass.For example: If you separate them to 3 times the original distance, the force ofattraction between them becomes1 / (3)2 = 1/9th of its original strength.
How does the force of gravity between two bodies change when the distance between them is increased by 4?
Provided neither mass changes, the mutual gravitational force of attraction betweentwo bodies decreases to 1/16 of its original value when the distance between theircenters increases to 4 times the original distance.

When the distance between two stars decreases by half the force between them will?
... increase to 4 times the original force.
How does the distance between two-interacting bodies affect the force of gravity?
Assuming the (toatal) mass doesnt alter Treat original distance as 1, the original force as 1 and new distance (d) as direct comparison to the old, then the force of gravity is: 1 / d2 Example: If the new distance is three times the original, then: f = 1 / 32 f = 1 / 9 = 0.111 times the original force. Example: If the new distance is half the original distance, then: f = 1 / 0.52 f = 1 / 0.25 = 4 times the the original force.
If the distance between two objects triples gravity will be?
... reduced to 1/9th of the original force.
