Only later in a second phase of development do students connect this with Newton's

law of gravitation itself and explore other consequences of that law, such as the orbital motions of satellites.

Newtons

Law of Gravitation, which was first articulated in his Philosophice Naturalis Principia Mathematica (1687) states that the gravitational force between two masses is proportional to the product of the two masses and inversely proportional to the square of the distance between them.

According to the Newtonian universal

law of gravitation, any two objects in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Then came one of the greatest minds ever, Sir Issac Newton, who combined the efforts of Kepler and Galileo through his

Law of Gravitation that showed that bodies in the heaven and on the earth obey the same universal laws.

"The scientists are right about the toast - pushing on that

Law of Gravitation proposed by the brilliant Isaac Newton, who had learnt if you stood under an apple tree for long enough, a pippin would drop on your head."

Tan (physics, Alabama A&M U.) brings the concepts to the introductory and intermediate undergraduate levels, working primarily from first principles and beginning with Kepler's laws of planetary motion and Newton's

law of gravitation. Thus armed, he explains the average and extremum values of variables, the central force problem, vector hodographs in planetary motion, planetary motion in Cartesian coordinates, the planetary problem in complex coordinates, Keplerian motion in the solar system, and planetary motion in three-dimensional space.

The showbiz queen of both New York and Hollywood blew her audience away with a performance of such class, pure emotion and physical exertion that it would have had Newton rewriting his

law of gravitation.

The showbiz queen blew her audience away last night with a performance of such class, pure emotion and physical exertion that it would have had Newton rewriting his

law of gravitation.

His greatest idea of all, fluxions and the

law of gravitation, came to him about 1666, when he was twenty-four ...

The exhibition's title refers to the gravitational constant, one of the most difficult values in physics to measure; although it appears in both Newton's

law of gravitation and Einstein's theory of relativity, it remains imprecise to this day.

I will also describe two equivalence experiments and a test of the inverse-square

law of gravitation. Finally, I will make some observations on the science of precision measurement--a subject that underpins much of scientific progress.
