If you say, double the distance, the force of gravity is one quarter
(f = 1/22 = 1/4)
If you say, treble the distance, the force of gravity is one ninth
(f = 1/32 = 1/9)
If you say, halve the distance, the force of gravity is four times
(f = 1/0.52 = 1/0.25 = 4)
In accordance to Newtonian gravitation, the acceleration of gravity is given by:
a=GM/r^2. This is a vector quantity, and thus can be decreased by other massive bodies. In addition to that, there is the fact that all objects do not have the same mass, and that the force is proportional to the inverse square of the distance to the center of mass. This means that depending on your distance to the center of mass, the value will be different.
The mass of an object does not change, regardless of gravity. If an object has 1 kilogram of mass, then it will have that much mass in space, where it weighs nothing, on Earth, or on Jupiter. Mass is a measure of the amount of "stuff", not the force of gravity upon that stuff.
Weight, on the other hand, measures the force of gravity pulling down on the mass. On Earth, our 1 kg object have about 9.8 Newtons of actual weight. In space, it has 0 Newtons, as it just floats away.
does anyone know, really need it for science classwork:)?
Force of gravity is not a constant. It will depend on the object mass, and distance between the 2 objects we are measuring. Refer to Newton's law of universal gravitation for more details.
The weight of the object changes, directly proportional to the sum of the mass of the object, and the increase in gravity. The mass itself remains unaltered.
The weight of the object would change if gravity changes.
cw: Yes, if the FORCE of gravity changes, the FORCE of the object in the downward direction changes.
No. Except for insignificant effects related to Special Relativity, the mass remains constant. The weight, on the other hand, changes. Weight is calcualted as: weight = mass x gravity Where "gravity" is the acceleration due to gravity.
No. Newtons are a measurement of mass and are relative only to Earth's gravity and are not affected by changes in gravity. Only weight is affected by changing gravity. On Earth, weight and mass are the same because Earth's gravity is the benchmark constant for measuring mass in Newtons, and weight is affected by that very same factor (Earth's gravity). On other planets, mass is unchanged because the Earthly gravity is a constant (and therefore, unchanged), and the weight changes because now it is affected by a new planetary gravity.
well weight depends on mass and gravity so gravity depends on mass. e.g weight=mass X gravity
Your mass never changes. Only your weight. Gravity does not affect mass.
Of course the objects mass will not change. Since there is no gravity in space(moon), only the objects weight will change.No matter where the object the mass will stay the same!
To get the weight, multiply the mass by the acceleration of gravity wherever the mass happens to be at the moment. Dependoing on local acceleration of gravity, the weight changes from place to place.
Mass . . . No change. Weight . . . Changes & depends on the gravity on the other planet compared to the gravity on Earth.
Your mass does not change. Your weight, however, changes in proportion to the gravity of each planet.
Mass will basically remain the same. As a reminder, weight = mass x gravity.
No. Only your weight does.
[ Mass ] is a property of the object, and doesn't depend on the presence or strength of gravity.[ Weight ] is the result of gravity, and changes depending on the local strength of gravity.
The mass(kg) of a human does not change, but the weight(N) of a human does. If gravity gets stronger, you get squashed(!), but if it gets lighter, you float around!
weight is defined as the product of mass and gravity constant. as the value of gravity changes weight is also changed
No. The mass of any object is constant wherever it is. Only its weight changes.
Mass does not change!!! Whatever the force of gravity, the object contains the same amount of matter. However, weight does change because the gravitational acceleration changes.
No. Except for insignificant effects related to Special Relativity, the mass remains constant. The weight, on the other hand, changes. Weight is calcualted as: weight = mass x gravity Where "gravity" is the acceleration due to gravity.
* Mass doesn't change because of conservation of mass. * Weight changes because it is the product of mass x gravity - and gravity on the Moon is less.
