Earth gravitational field strength
WebSep 16, 2024 · Between the poles of Earth and its equator the gravitational field strength varies since the Earth is not perfectly spherical. The measured value of g (and apparent weight) also vary because the Earth is spinning. 1. Taking the radius of the Earth to be 6.4 x 10^6 m, calculate the centripetal force on a 1 kg mass on the equator.

The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation). It is a vector quantity, whose direction coincides with a plumb bob and strength or magnitude is given … See more A non-rotating perfect sphere of uniform mass density, or whose density varies solely with distance from the centre (spherical symmetry), would produce a gravitational field of uniform magnitude at all points on its See more Gravity acceleration is a vector quantity, with direction in addition to magnitude. In a spherically symmetric Earth, gravity would point directly towards the sphere's centre. As the Earth's figure is slightly flatter, there are consequently significant deviations in the direction of … See more From the law of universal gravitation, the force on a body acted upon by Earth's gravitational force is given by $${\displaystyle F=G{\frac {m_{1}m_{2}}{r^{2}}}=\left(G{\frac {M_{\oplus }}{r^{2}}}\right)m}$$ where r is the … See more • Earth sciences portal • Escape velocity – Concept in celestial mechanics • Figure of the Earth – Size and shape used to model the Earth for geodesy See more Tools exist for calculating the strength of gravity at various cities around the world.
