Yes.
No, there is no mass there to have any gravitational force.
No, there is not.
Physically put, No. A vacuum has no particles of gas in it, but there is still gravity it just has nothing to act upon. Philisophically, it is much like the tree falling in the woods with no one there to hear it. That is to say the gravity only exists if it can be perceived by one of the senses.
In a vacuum, the force of attraction between two objects is determined by their masses and the distance between them, as described by Newton's law of universal gravitation. This force decreases as the distance between the objects increases and increases as the masses of the objects increase.
Yes. The gravitational attraction between the sun and earth is what keeps the earth bound to the sun in orbital motion, even though there's 93,000,000 miles of total vacuum between them. Nothing is known that can 'shield' or stop gravitation from going through it.
Yes. Gravity attracts every speck of mass in the universe to every other one, even though in almost all cases, there's nothing but vacuum between them.
If the gravitational force is less than the buoyant force, the drag force will act in the opposite direction of the gravitational force.
how is weight affected by gravitational force?
Gravitational force is the strongest when you are the closest to a mass.
= What is the gravitational force called gravity? =
Mars has a gravitational force of 3.7m/s2.
A black hole is an area in space that acts like a vacuum cleaner, exerting a strong gravitational pull on surrounding matter and light. This gravitational force is so powerful that not even light can escape from it, giving it its characteristic black appearance.
