  2. Gravitational field - Wikipedia

    en.wikipedia.org/wiki/Gravitational_field

    In classical mechanics, a gravitational field is a physical quantity. [5] A gravitational field can be defined using Newton's law of universal gravitation. Determined in this way, the gravitational field g around a single particle of mass M is a vector field consisting at every point of a vector pointing directly towards the particle. The ...

  3. Gravitational energy - Wikipedia

    en.wikipedia.org/wiki/Gravitational_energy

    The gravitational potential energy is the potential energy an object has because it is within a gravitational field. The magnitude of the force between a point mass, M {\displaystyle M} , and another point mass, m {\displaystyle m} , is given by Newton's law of gravitation : [ 3 ] F = G M m r 2 {\displaystyle F={\frac {GMm}{r^{2}}}}

  4. Compact object - Wikipedia

    en.wikipedia.org/wiki/Compact_object

    Adding any extra mass to the black hole will cause the radius of the event horizon to increase linearly with the mass of the central singularity. This will induce certain changes in the properties of the black hole, such as reducing the tidal stress near the event horizon, and reducing the gravitational field strength at the horizon.

  5. Gravimetry - Wikipedia

    en.wikipedia.org/wiki/Gravimetry

    Gravimetry is the measurement of the strength of a gravitational field. Gravimetry may be used when either the magnitude of a gravitational field or the properties of matter responsible for its creation are of interest. The study of gravity changes belongs to geodynamics.

  6. Gravitational acceleration - Wikipedia

    en.wikipedia.org/wiki/Gravitational_acceleration

    Vector field (blue) and its associated scalar potential field (red). Point P between earth and moon is the point of equilibrium. In physics, a gravitational field or gravitational acceleration field is a vector field used to explain the influences that a body extends into the space around itself. [6]

  7. Jupiter - Wikipedia

    en.wikipedia.org/wiki/Jupiter

    Jupiter's magnetic field is the strongest of any planet in the Solar System, [102] with a dipole moment of 4.170 gauss (0.4170 mT) that is tilted at an angle of 10.31° to the pole of rotation. The surface magnetic field strength varies from 2 gauss (0.20 mT) up to 20 gauss (2.0 mT). [122]

  8. Gravity map - Wikipedia

    en.wikipedia.org/wiki/Gravity_map

    Goddard Mars Model (GMM) 3 is a gravity map of the gravitational field on the planet Mars. [2] Three orbital craft over Mars, the Mars Global Surveyor (MGS), Mars Odyssey (ODY), and the Mars Reconnaissance Orbiter (MRO) assisted in the creation of the GMM 3 by the study of their orbital flight paths. [2]

  9. Introduction to general relativity - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_general...

    In a similar way, Einstein predicted the gravitational deflection of light: in a gravitational field, light is deflected downward, to the center of the gravitational field. Quantitatively, his results were off by a factor of two; the correct derivation requires a more complete formulation of the theory of general relativity, not just the ...
