Is the the force increased to twice as much when the distance between two stars decreases by half?
It is 4 times bigger. Newton's Law of Gravitation says that the gravitational force between two objects is inversely proportional to the square of the distance between them. More specifically F = (G*m1*m2)/(r2). If you cut the distance in half, you have to square that, which is 1/4 so the force is 4 times bigger.
Why is gravitational force important to your universe?
As a big part, the gravitational force is what keeps us on the earth but other things make it necessary like the creation of elements in stars and light bending around objects like black holes and stars.
How many basic forms of energy are there?
Theres the ball driver, and the Force of the stars. Darth Vader has Force Choke and Sith Lightning which can help alot.
What is gravity and does the size of 2 objects and the distance between them affect the gravitational force?
Gravity or gravitation is a natural phenomenon by which all things with mass-energy are brought toward one another, including stars, planets, galaxies and even light and sub-atomic particles.No, the gravitational force does not depend on the size of the objects. It depends on the mass-energy of the objects. While larger objects CAN contain more mass-energy and thus experience larger gravitational forces, objects can be large but have very low density thus have very little mass-energy.
Equation for gravity?
Newton's Law of Gravitation states that the Force of Gravity between two objects is equal to the Gravitational Constant times product of the masses of the two objects, divided by the square of the distance between them.The Gravitational Constant is around 0.00000000006 (or 6 x 10 to the power of minus 11), and its symbol is Gm1 is the mass of one objectm2 is the mass of the other objectd is the distance between themF is the Force between the two objectsso:F = (G x m1 x m2) / (d x d)-----------------------------------------------------------------------------Newton's law of universal gravitation is generally what is used to calculate the force of gravity between two objects. Note that this equation does not work when dealing with the force of gravity in very massive, dense objects (eg. black holes, neutron stars); for those situations you must go to Einstein's theory of general relativity.from Wikipedia:F = G*((m1*m2)/r2)F is the magnitude of the gravitational force between the two point masses,G is the gravitational constant, 6.674×10−11 N m2 kg−2m1 is the mass of the first point mass,m2 is the mass of the second point mass, andr is the distance between the two point masses.
Is there gravity in space and why?
Yes. Gravity is a force of attraction that exists between all objects with mass. It increases with the mass of the object in question and decreases with distance from it. Planets, stars, moons, and galaxies all exert a gravitational pull.

Compare the distance between two stars and the distance between two planets?
The distance between stars are much greater than distances between objects in our solar system
What is a cosmic distance?
A distance in space, between stars etc.
What units are for distance between stars?
The correct unit to describe the distance between stars is the "light year", the distance a photon of light would travel (through a vacuum) in a year.
What is the distance between star?
The distance between stars can be anything from light minutes to billions of light years.
Are the stars measured in light years?
Stars are not measured in light years. The distance between them is.
What do astromoners measure distance in between stars with?
light years
What is the distance between (-3,6),(-3,-2)?
The distance between stars can be anything from light minutes to billions of light years.
What unit of distance would you use to measure the distance between two stars?
Light Years.
What are two factors that affect gravitational pull?
Mass of the objects, and distance between them (And they don't have to be in space. It can just as well be the gravitational force between the lint in your pocket and a grain of sand on the beach in South Africa. The same formula accurately calculates the magnitude of that force.)
Why is using a light year useful for measuring stars?
Because the distance between stars is so great.
