The gravitational constant, G (big G), is a physical constant that doesn't change at all. The magnitude of gravitational acceleration, g (little g), has no effect on G.
Little g is used as an approximation for near-surface gravity of a planet (or other large mass). The reason it is used is because the formula for universal gravity and Newton's second law:
- F = G (mplanet*mobject)/(r3) -- r is the distance between the centers of mass
- F = mobject*aobject
- aobject = G (mplanet)/r3
We call the above magnitude, g. Each planet has its own g and Earth's is about 9.8 m/s2.

How does gravitational force effect a space traveler?
On launch, the gravitational force increases their body weight by about three or four times, and their blood tries to stay grounded, sending the body into chaos.
Where is its gravitational potential energy minimum?
The answer depends on what "it" is and the overall context. The answer could be the centre of the earth where the earth's gravity has no effect, or the Lagrange point where the gravitational forces of the moon, earth and sun balance each other.
What is the mechanical advantage of an inclined plane if it were on the moon instead of the earth?
Exactly the same. The reduction in gravitational force has no effect on M.A., which is a matter of simple geometry.
What will be the weight in kg of 1 liter of furnace oil having specific gravity of 0.9655?
Mass is measured in kilograms, not weight. The mass of the furnace oil will be 0.9655 kg. If you do not know the difference between weight and mass, consider the following: You have the same amount of material in you whether you are in earth, in mid space or on the moon. That is your mass. You also have a certain amount of weight on earth, which is the effect of the earth's gravitational force acting on your mass. On the moon, the gravitational force is only a sixth as strong and your weight will be only a sixth as much as on earth. In outer space, there may be no gravitational force in which case your weight will be 0. Thus your mass is something that is an intrinsic property of you (at least, of your body) while your weight is largely dependent on the gravitational force acting on you.
When elevator move down with acceleration pendulum of bob what is effect on time period?
When the elevator starts moving down, the time period increases. But when the elevator is descending at a constant velocity, the time period returns to its normal.

How do mass and distance effect gravitational force?
The gravitational force between two objects increases with mass: the larger the mass, the stronger the gravitational force. The force decreases with distance between the two objects: the farther apart they are, the weaker the gravitational force.
What is acceleration deu to gravity"g"?
Acceleration due to gravity "g" is produced by a gravitational force. This can be understood through Newton's law of gravitation: Law of Gravitation: F = (G * m1 * m2) / r^2 where, F is the gravitational force, G is the gravitational contraction number (used in the gravitational formula), m1 and m2 are the masses of two objects, r is the distance between two objects. It follows from this formula that the force of gravity is universal in relation to the velocity and distance between the two objects. "g" here stands for gravitational contraction number or gravitational contraction number of gravitational space (gravitational constant). Because its value is very small, the effect of gravity on the gravitational force is not very strong. It is resorted to by humans at almost all lengths and times. Acceleration of an object with the Earth by gravity "g" is a quantity of energy, which is very small in a single month's mass in a single time. It is important to note that "g" deals with the acceleration of the object relative to Earth, and does not focus on the overall acceleration.
What is the effect of mass of freely falling body on the gravitational acceleration?
No effect whatsoever. Without air to interfere with the effects of gravity, a small feather and a large rock fall with the same acceleration.
Does speed affect gravitational potential energy of an object?
No, speed does not directly affect the gravitational potential energy of an object. Gravitational potential energy depends on an object's mass, height above a reference point, and the acceleration due to gravity, but not its speed.
What is the effect of gravitational acceleration specially on the head of a person?
Gravitational acceleration pulls the head downward, causing a sensation of weight on the neck muscles. This force can lead to neck strain and discomfort if the head is not properly supported, such as when sitting or standing for extended periods. Proper posture and exercises can help alleviate some of the strain caused by gravitational acceleration on the head.
What effect does the planet have on gravitational potential energy?
The planet IS the source of gravitational (potential) energy.
What's the difference between the gravitational effect on earth and the gravitational effect on Uranus?
the man was fatter than i could imagine
What is the effect of mass on the gravitational attraction between objects?
If there is more mass, there will be more gravitational attraction.
What are the variables that effect the strength of gravity?
The strength of gravity is primarily determined by two variables: the mass of the objects involved and the distance between them. The greater the mass of the objects, the stronger the gravitational force. Conversely, the farther apart the objects are, the weaker the gravitational force.
How do differences in an objects mass impacts its gravity pull?
Pull of gravity of earth increases with increase in mass of the object. This pull of gravity is called "Weight" of the body. But remember, this increase in pull does not results in increase in value of acceleration( called gravitational acceleration g). Because, according to Newton s second law of motion,F=ma or a=g=F/m, as pull of earth "F" is increased, but along with it, mass"m" is also increased, so both things cancel the effect of each other and acceleration remains constant. That is why, value of gravitational acceleration "g" always stays constant.(9.8ms-2).
