The force on an object of mass m1 near the surface of the Earth is F m1g This force is provided by gravity between the object and the Earth according to Newtons gravity formula and so you can write The radius of the Earth re is about 638 10 6 meters and the mass of the Earth is 598 10 24 kilograms. The equation above is a mathematical model of the albedo of a dust grain Am as a function of its index of refraction m which is a complex number of the form m a - bi. Each tensor has 10 independent components.
There is of course no end to the number of mathematical formulas and expressions that exist some might say the list is infinite but here we focus on some of the better known.
Plugging this into the formula for area we get A L 250 - L 250L - L2 -L2 250L. On earth the force due to gravity between Earth and an object on earth can also be related to the same formula. The EFE is a tensor equation relating a set of symmetric 4 4 tensors. These equations together with the geodesic equation which dictates how freely falling matter moves through spacetime form the core of the mathematical formulation of general relativity.
