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.
No. The Sun still attracts the Earth, and the Earth attracts the Moon, despite the vacuum. The gravitational force depends only on the masses involved, and on the distance. There is no known way to "shield" the gravitational force.
yes
-- The more mass an object has, the more gravitational force there is betweenit and the Earth.-- But the more mass an object has, the more force is required to accelerate it.-- The relationship between how much gravitational force there is and how much forceis required trades off just right, so that every mass has the same acceleration.
Down ward force is greater than upward force because everything on earth, obeys the laws of gravity, and for a rocket to take off from earth it needs more energy in other to fight the earths gravitational force but despite fighting the gravitational force it still doesnt take off with a full speed, But for a body of mass to fall from the atmosphere its falls with a great speed due to the force of the earths gravity.
Yes, because you attract the earth with the same gravitational force that the earth attracts you.
The mass of an object is constant unless you physically add to it or cut part of it off. It will not increase when an object is pulled by a constant force.
system isolated and the vacuum pump turned off.
yes

Gravitational Force
If the rockets are active then you will feel a gravitational force pulling you down in the direction opposite the rocket's motion. If they are off however you are weightless and you experience no gravitational force.
No. It's the mutual gravitational force between it and the earth that keeps a satellitein a closed orbit, instead of flying off away from earth in a straight line.Technically, there's no such thing as "outside of" the gravitational force of anything.We can calculate the gravitational force between a star in a distant galaxy and the earth.In fact, we can calculate the gravitational force between a star in a distant galaxy and you.The force is pretty small, but it's there.
Weight = mass * gravitational field strength W = mg The force to lift off is the force to overcome the force of weight. As the mass doesn't change, the only variable affecting W is g, the gravitational field strength. Which planet has the highest gravitational field strength, and that is your answer. (you probably have this in a data book or something, for reference, earth's gravitational field strength is 9.81 ms^-2 , sometimes simplified to 9.8 or 10) Once you have worked out your answer, you should have got the planet: Jupiter. I hope this helped, Ibraheem.U
the moon rotates around the earth. The force keeping it in orbit around the earth aka the centripital force is caused by the gravitational force between the moon and the earth. If the gravitational force and thus the centripital force dissapeared, the moon would fly off tangent to its circular orbit
I guess around 2 G's
The actual gravitational force on the astronaut ... the force attracting him to themass of the earth ... is exactly the same as it always is, and is equal to his weight.But ... he feels as if there's more force on him, as if his weight has increased.That's because he's accelerating aboard the launch vehicle, and there's no wayto tell the difference between the force of gravity and the force of acceleration.
Yes, she was once spanked with a spatula, but most of the time with a vacuum.*******Most of the time, a spanking with a vacuum is not possible, unless it is turned off.
The ignition is turned on and off with the vacuum line. If the vacuum line leaks or gets plugged, the engine won't turn off. Then you'll have to open the hood and push the red "Stop" lever on the engine.
