Isaac Newton helped to explain Kepler's law of planetery motion by duoing his theory of what?

Answer 1

Kepler came up with three laws: (1) Planetary orbits are elliptical (not circular) with the sun at a focus; (2) a planet's radius vector (a line from the sun to the planet) sweeps across equal areas in equal times; and (3) the cube of the planetary period (the time taken by one orbit) divided by the square of the planet's mean distance from the sun is a constant ratio for all planets.

The second law implies that planets travel faster when they are closer to the sun.

Coming up with these laws was no mean feat. The laws certainly were not obvious, and it took a huge amount of effort, dedication, time, and insight to get them. Nevertheless, all of the laws were descriptive in nature, and none suggested why they should be as they are.

Newton's Theory of Universal Gravitation explained all of it. Gravitational attraction is directly proportional the product of the masses (the sun and the planets) and inversely prfoportional to the square of the distance.

Everything follows from that.

Answer 2

He mentions the big bang and evolution together. In the eyes of some creationists, these go together because they both claim that God's creation changes over time. That's right, all the cosmologists are disciples of Darwin?! He quotes Rob Roselli as the source of his ideas about Newton's Laws of Motion, and Kepler's Laws of Planetary Motion. I found Roseli's web site (2nd link below) - but got severe mental indigestion, so I did not read much of it!

Answer 3

If you take Newton's Laws of Motion and the Law of Universal Gravitation, you can mathematically derive Kepler's Laws. Some of the math gets a little hairy, though. You can also use other physics laws to get Kepler's Laws, but those other laws are based on Newton's Laws in the end, anyway.

Answer 4

"Newton's great insight of 1666 was to imagine that the Earth's gravity extended to the Moon, counterbalancing its centrifugal force. From his law of centrifugal force and Kepler's third law of planetary motion, Newton deduced that the centrifugal (and hence centripetal) force of the Moon or of any planet must decrease as the inverse square of its distance from the center of its motion. For example, if the distance is doubled, the force becomes one-fourth as much; if distance is trebled, the force becomes one-ninth as much. This theory agreed with Newton's data to within about 11%. "

in short: "Sir Isaac Newton: The
Universal Law of Gravitation"
