Wide holes were opened in the Newtonian theory that two bodies always attract each other with a force proportional to the square of the distance between them.

Thus, emitter theory combines electrodynamics and mechanics with a simple Newtonian theory.

He brought forward questions on the Newtonian theory; and divided candidates into two classes.

This caused some people to not agree with Newtonian theory.

Even in the simpler Newtonian theory of gravity, one can solve the equations exactly only in the case of two particles.

The first term agrees with the corresponding solution in the Newtonian theory of gravitation and the one in general relativity.

In regions which are significantly denser than the background, the full Newtonian theory of gravity must be included.

It was a sensational moment of 19th century science and dramatic confirmation of Newtonian gravitational theory.

The classical Newtonian theory of gravity is recovered in the limit as the ratio r/r goes to zero.

Heavenly bodies such as comets with parabolic or even hyperbolic orbits are possible under the Newtonian theory and have been observed.
