The Newtonian model of gravity in which the force between two objects is given by $F=\frac{GMm}{r^2}$ and mass is the source, or cause, of gravitation. Newtonian concepts also include the gravitational field, the gravitational potential energy, and the gravitational potential.
Newtonian gravity can also be formulated in terms of Poisson's equation $\nabla^2\Phi=4\pi G\rho$.
