The path of the planets about the sun is elliptical in shape, with the center of the sun being located at one focus.

Example: The planets orbit the Sun in ellipses with the Sun at one focus]]> 2018-02-06 14:16:34 UTC https://padlet.com/orsojerneigh/udyrr4namf4o/wish/228601658 orsojerneigh https://padlet.com/orsojerneigh/udyrr4namf4o/wish/228602744 The Law of Equal Areas

An imaginary line drawn from the center of the sun to the center of the planet will sweep out equal areas in equal intervals of time.

Example: The line joining the Sun and a planet sweeps through equal areas in an equal amount of time.]]> 2018-02-06 14:18:09 UTC https://padlet.com/orsojerneigh/udyrr4namf4o/wish/228602744 orsojerneigh https://padlet.com/orsojerneigh/udyrr4namf4o/wish/228603586 The Law of Harmonies

The ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun.

Example: The square of the period of a planet’s orbit is directly proportional to the cube of the semimajor axis of its elliptical path.]]> 2018-02-06 14:19:19 UTC https://padlet.com/orsojerneigh/udyrr4namf4o/wish/228603586 orsojerneigh https://padlet.com/orsojerneigh/udyrr4namf4o/wish/228616064 Kepler's laws and Newton's laws taken together imply that the force that holds the planets in their orbits by continuously changing the planet's velocity so that it follows an elliptical path is directed toward the Sun from the planet, is proportional to the product of masses for the Sun and planet, and is inversely proportional to the square of the planet-Sun separation.]]> 2018-02-06 14:37:23 UTC https://padlet.com/orsojerneigh/udyrr4namf4o/wish/228616064 orsojerneigh https://padlet.com/orsojerneigh/udyrr4namf4o/wish/228616633 conservation of angular momentum states that when no external torque acts on an object, no change of angular momentum will occur. The conservation of angular motion actually explains Kepler’s second law of planetary motion. According Kepler’s second law of planetary motion, as a planet moves around its orbit, it sweeps out equal areas in equal time.]]> 2018-02-06 14:38:11 UTC https://padlet.com/orsojerneigh/udyrr4namf4o/wish/228616633 orsojerneigh https://padlet.com/orsojerneigh/udyrr4namf4o/wish/228949655 2018-02-07 04:47:49 UTC https://padlet.com/orsojerneigh/udyrr4namf4o/wish/228949655 orsojerneigh https://padlet.com/orsojerneigh/udyrr4namf4o/wish/228949776 Johannes Kepler was born on December 27, 1571 in Weil der Stadt, Württemberg, Germany.
