-
Atoms are held together with attractions, also called forces.
-
German mathematician, atronomer, and astrologer. Law of Planetary motion,
First Law: Planets move around the Sun in ellipses, with the Sun at one focus
Second Law: The line connecting the Sun to a planet sweeps
equal areas in equal times.
Third Law: The square of the orbital period of a planet is proportional to the cube of the mean distance from the Sun -
