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
yields (when set equal and dividing out the mass of the object):
  • aobject = G (mplanet)/r3
As you can see, the acceleration due to gravity won't change much for distances near the planet's surface.

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.


What effect does the planet have on gravitational potential energy?

The planet IS the source of gravitational (potential) energy.


What would be the effect on mass and the weight of an object were taken to a planet with twice the gravity ofearth?

The mass of the object would remain the same, as mass is a measure of the amount of matter in an object. However, the weight of the object would double on a planet with twice the gravity of Earth, since weight is the force exerted on an object due to gravity and is dependent on the mass and the gravitational acceleration of the planet.

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.


The effect of gravity on matter is the measureof?

The effect of gravity on matter is measured by its mass and distance from other objects. Gravity causes matter to be attracted to each other, creating phenomena such as gravitational waves and orbits. The strength of gravity between two objects is determined by the product of their masses and inversely proportional to the square of their distance.


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.
