Isaac Newton’s Universal Law of Gravitation

Isaac Newton’s Universal Law of Gravitation

Note by nextexx.com ed:

theguardian.com: Newton’s equation first appeared in the Philosophiæ Naturalis Principia Mathematica, July 1687. It describes why that apple fell from that tree in that orchard in Lincolnshire. Whether or not that apple actually landed on Isaac Newton’s head, as some stories would have it, this equation describes why you stay rooted to the ground, what locks the Earth in orbit around the sun and was used by Nasa engineers to send men to the moon.

Here is the NASA page that describes the motions of the moon using Newton’s formulas although it says: Disclaimer: The following material is being kept online for archival purposes.

Any claim that Newton has been superseded by modern methods needs to explain why NASA used Newton’s methods in it’s exploration of the moon or show that it did not – something I personally do not think is possible. So go ahead!

Wiki: “The basic SI unit of mass is the kilogram (kg). In physics, mass is not the same as weight, even though mass is often determined by measuring the object’s weight using a spring scale, rather than balance scale comparing it directly with known masses. An object on the Moon would weigh less than it does on Earth because of the lower gravity, but it would still have the same mass. This is because weight is a force, while mass is the property that (along with gravity) determines the strength of this force.”

Mass is location dependent and using a spring that is also dependent on gravity pulling a weight down makes no difference. A mass or weight will still be less on a smaller body like the Moon. The weight of the SI kilogram is a ratio of the kilogram and the Earth, away from the Earth that ratio disappears.
