What would be the acceleration due to gravity of a planet that has 9.3 m earth and 4 r earth?
SydneeKennedy
The acceleration due to gravity is proportional to mass and inversely proportional
to the square of distance. So, the acceleration of gravity on the surface of such
a planet, compared to that on the surface of the Earth, would be
(Agrav on Earth) x (9.3/16) = 5.7 meters (18.7 feet) per second2 (rounded)

How do rockets stay up in the air?
Rockets stay in the air so long as they are burning enough fuel to overcome the acceleration of gravity. Let me explain. For something to leave the surface of a planet, in our case that planet would be the Earth, it must overcome gravity. Gravity on the earth has a constant acceleration about 9.8 m/s that points toward the center of mass of the earth, which is somewhere near it's core. Now to overcome that force a rocket must have an anti-parallel acceleration that is greater than that of gravity. A rocket achieves the necessary acceleration by burning fuel that provides propulsion. So long as the rocket is burning enough fuel to keep it's acceleration above that of gravity it will stay in the air.
Does Pluto have a greater or less gravity than earth?
Earth has a much greater mass than Pluto does, and therefore has stronger gravity.
How does the force due to gravity on Mars compare to the force due to gravity on Earth?
The acceleration of gravity at the surface of Mars is approximately 3.7 m/s2. Earth's acceleration is 9.8 m/s2 on average. The force that gravity would exert on an object is dependent on its mass.
Would a person be squashed by the extreme gravity on planet mercury?
Mercury does not have extreme gravity. Its gravity is only 38% of Earth's. If you are talking about Jupiter, then yes.
How much would you weigh on Super-Earth?
Please tell me the acceleration of gravity on the surface of Super-Earth, and I'll be happy to work it out for you.
What would be the effect on the mass and the weight of an object if the object weas taken to a planet with twice the gravity of earth?
Mass is not affected by gravity, so it would have the same mass. Weight, on the other hand, is affected by gravity, and would double when on the planet as compared to when it is on Earth (w=mg, where w=weight, m=mass, g=gravitational acceleration also called strength of gravity)
What would be the gravity in relatation to earth of a planet with 3.4 times the gravity on earth?
You already stated in the question that it has 3.4 times the gravity of Earth.

How much would an object with a mass of 5 kg weigh on Planet A?
Well you would need to know the force of Gravity on the surface of Planet A to answer this. The equation to use would be 5 multiplied by the force of gravity on Planet A = the weight in kilograms. So if Gravity on planet A was twice that on Earth then it would weigh 10Kg and if it was 1/2 that on Earth it would weigh 2.5 kg.
Is it true that a abject that weighs 100 pounds on earth would weigh over a ton on the sun?
The mass of the sun is many times that of the earth, the result is that the acceleration of gravity is also much greater. Since the acceleration of gravity on the sun is higher, and the weight of an object is based on its mass and acceleration of gravity, the object would weigh considerably more
Is gravity on earth greater or less then gravity on Venus?
The gravity present on a planet is usually denoted by the acceleration an object would experience due to gravity on that planet's surface. If we stick to Newtonian gravity (which should be adequate for our present purpose) the acceleration due to gravity on a planet is given by: a = G*M / R^2 Where G is Newton's gravitational constant, M is the mass of the planet, and R is its radius (remember we are standing on the surface). (Note: Here I have neglected the vector qualities of acceleration, this will not matter at present, the acceleration will be pointing down, towards the center of the planet.) From this formula we can see that the acceleration increases if the mass of the planet increases. This is to be expected; gravity (in Newtonian gravity) is caused by mass, and thus a bigger mass means a stronger gravitational field. Since Venus is less massive than Earth we might expect the surface gravity on Venus to be less than on Earth. However, we also have the R^2 in the denominator. This means the surface gravity on a planet will increase if the radius decreases (and the mass stays the same). This is also clear; if the radius is less then you stand deeper into the gravitational field. Venus is about the same size as Earth so this effect should not play as much a role as the difference in mass does. Thus, just by using these arguments we can already conclude that the surface gravity on Earth is larger than the surface gravity on Venus. Let us now look at some numbers. Earth's surface gravity is about 9.81 m/s^2 (it varies slightly from location to location). And Venus' surface gravity is 8.87 m/s^2, which is less, as expected. This means that if you weigh 70 kg on Earth you will weigh 70*(8.87/9.81) = ~63 kg on Venus.
Would the gravity on the planet Mercury squash someone?
No. The gravity on Mercury is less than half that of Earth.
What happen to the acceleration due to gravity if earth stop revolving?
GRAVITYThe acceleration due to gravity is a force related to Earth's mass and is not dependent on its rotation - gravity would not change if the Earth ceased to rotate. WEIGHT However, if the Earth ceased to rotate, someone standing on the equator would weigh more - this increase in weight effect would decrease as you moved the person to the poles to do the comparison.
How much more is the gravitational force of the earth than the moon?
The acceleration of gravity on the moon is about 1/6th the acceleration of gravity on earth. Any mass on the earth's surface feels about 6 times the downward force that it would feel on the surface of the moon.
How would your weight change on the surface of an earth sized planet whose mass was greater than earth why?
Your weight is directly proportional to the mass and gravity of the planet, if the planet has a greater gravity and mass, you will weigh more.
