Kepler's law: in equal intervals of time, the areas swept out in space by an imaginary line connecting the Sun and a planet are always equal Kepler's law: the orbits of all the planets are ellipses Kepler's first law Orbital period; semimajor axis Kepler's second law Kepler's third law: units of P and a P = years, a = astronomical unit (AU) Kepler's third law: The square of a planet's _____ is directly proportional to the cube of the ______ of its orbit Kepler's three laws provide a precise geometric description of _________ within the framework of the _____ system planetary motion; Copernican Lippershey's telescope influenced this person to create his own as well and proceeded to do astronomical observations with it and later proving the Sun is the center of the universe Galileo Galilei Masses in the universe interact via what force? Gravity Most eccentric orbit Mercury (0.21) Newton concluded that the magnitude of the force of gravity must _______with increasing distance between the Sun and a planet (or between any two objects) in proportion to the inverse _________ of their separation. In decrease; square Measure of a body's motion Momentum Most important idea in Copernicus' De Revolutionibus Earth is one of the planets revolving around the Sun Newton derived Kepler's third law by adding ___ to its concept and equation mass of two interacting bodies Mercury's orbital speed (highest among the planets) 48 km/s Neptune's orbital speed (lowest among the planets) 5 km/s Newton's Universal Law of Gravitation's formula Fg = G(M1M2/R^2)
