Here, students learn Newton's

law of gravitation and use this to study motion on an inclined plane, projectile motion and planetary (orbital) motion.

The final measurement in this group of related experiments was a test of the inverse-square

law of gravitation on the scale of meters to kilometers.

He had proposed that religion be "alive and warm, part of human life, and of the landscape, and of the cheerful day," (29) and foretold a teacher who would see "the identity of the

law of gravitation with purity of heart.

The finding demonstrated that the pairs of stars move in accordance with Newton's

law of gravitation, "extending [the law] farther into space than ever before," notes DeVorkin.

As example the well-known story of Newton's (Albertyn, 1955: 1764-1765) formulation of the Universal

Law of Gravitation is used: One day Newton was sitting dreaming under a tree.

8 times gravity, the plane begins to crest in its arc of travel, and the

law of gravitation seems for a startling moment to be suspended.

He said he discovered the universal

law of gravitation by thinking about it.

And, as an undergraduate, I was told about Newton's religiosity (by one of my more renegade physics teachers)--but again, so what for the inverse square

law of gravitation and for celestial mechanics?

After the formulation of the

law of gravitation, a few conservative biblical commentators sought to explain "chains" and "cords" in the Job 38:31 passage, "Can you bind the chains of the Pleiades, or loose the cords of Orion?

Newton's

law of gravitation is still valid in all contexts except those in which the objects are travelling at or near the speed of light.

The whole story is usually regarded as the greatest victory that Newton's

law of gravitation was to achieve, for a tiny apparent deviation from that law was enough to lead to the discovery of a giant planet.

For example, Newton's

law of gravitation has already been given this form and the equations of general relativity theory and of fluid dynamics can, in principle, be expressed in this way.

By watching an apple fall from the tree, Isaac Newton was able to develop the Universal

Law of Gravitation.

Milgrom [1] proposed an alternative explanation for the "galaxies rotation curves", by modifying Newton's

law of gravitation, for which he needed an ad-hoc introduction of a new constant of nature [a.

These two laws, Kepler's third law and Newton's

law of gravitation, afford the opportunity of probing a little more deeply into the epistemological nature of such "laws of nature.
