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.

Is gravitational force acting on a person who falls off a cliff?
yes
Why is the acceleratoin due to gravity the same for all objects?
-- 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.
How big is the upward force compared to the downward force?
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.
You jump off a truck and accelerate toward the surface of the Earth Does the Earth accelerate toward you?
Yes, because you attract the earth with the same gravitational force that the earth attracts you.
When the mass of an object increases its gravitational pull .?
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.
Measuring a final system vacuum is done with the?
system isolated and the vacuum pump turned off.
Is gravitational force acting on a person who falls off a cliff?
yes
What invisible force holds you onto the earth so that you don't simply fall off?
gravitational force
The force that keeps objects from floating off into space is known as what?
Gravitational Force
Is there gravity in a rocket ship?
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.
Are satellites outside the earths gravitational pull?
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.
Which planet would a spaceship need the largest force to take off?
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
How would the motion of the moon change with no centripital force?
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
What is the peak gravitational force of big daddy rocket during lift-off?
I guess around 2 G's
What is the gravitational force acting upon an astronaut when lifting off?
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.
Has Madison pettis ever been spanked if so with what?
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.
What vacuum valve is located behind the ignition switch of a Mercedes Benz 300 turbo Diesel?
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.
