WebApr 9, 2024 · Gravitational field's dependence on distance from source: ... Now, if we surround \(m_s\) with an imaginary sphere, it is clear that no matter how large or how small the sphere, the same number of field lines from \(m_s\) will penetrate the surface of the sphere. However, the density of the field lines which penetrate the surface will decrease ... WebThe gravitational field is the spatial derivative of the gravitational potential. Therefore, gravitational potential has units of length squared over time squared, or more simply, velocity squared . Conversely, from the Poisson equation, we have that \(G\times\mathrm{density}\) has the same units as the spatial derivative of the … bob hoye articles
