  2. Gravity of Mars - Wikipedia

    en.wikipedia.org/wiki/Gravity_of_Mars

    The gravity of Mars is a natural phenomenon, due to the law of gravity, or gravitation, by which all things with mass around the planet Mars are brought towards it. It is weaker than Earth's gravity due to the planet's smaller mass. The average gravitational acceleration on Mars is 3.728 m/s 2 (about 38% of the gravity of Earth) and it varies. [1]

  3. List of equations in gravitation - Wikipedia

    A common misconception occurs between centre of mass and centre of gravity.They are defined in similar ways but are not exactly the same quantity. Centre of mass is the mathematical description of placing all the mass in the region considered to one position, centre of gravity is a real physical quantity, the point of a body where the gravitational force acts.

  4. Equations for a falling body - Wikipedia

    en.wikipedia.org/wiki/Equations_for_a_falling_body

    A set of equations describing the trajectories of objects subject to a constant gravitational force under normal Earth-bound conditions.Assuming constant acceleration g due to Earth's gravity, Newton's law of universal gravitation simplifies to F = mg, where F is the force exerted on a mass m by the Earth's gravitational field of strength g.

  5. Newton's law of universal gravitation - Wikipedia

    This formulation is dependent on the objects causing the field. The field has units of acceleration; in SI, this is m/s 2. Gravitational fields are also conservative; that is, the work done by gravity from one position to another is path-independent. This has the consequence that there exists a gravitational potential field V(r) such that

  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. Gravity of Earth - Wikipedia

    en.wikipedia.org/wiki/Gravity_of_Earth

    g h is the gravitational acceleration at height h above sea level. R e is the Earth's mean radius. g 0 is the standard gravitational acceleration. The formula treats the Earth as a perfect sphere with a radially symmetric distribution of mass; a more accurate mathematical treatment is discussed below.

  8. Theoretical gravity - Wikipedia

    A similar model adjusted for the geometry and gravitational field for Mars can be found in publication NASA SP-8010. [4] The barycentric gravitational acceleration at a point in space is given by: = ^ where:

  9. 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.
