Step 1 of 3

The Legend of the Falling Apple - Newton was not the first to discover gravity. Newton discovered that gravity is universal. - Legend—Newton, sitting under an apple tree, realized that the force causing an Apple to accelerate downward is the same force causing the Moon to move in circular path around the earth - Newton was the first to realize that the Moon is constantly falling toward the earth Astronomy - Earliest Babylonian star catalogs are dating from about 1200 BCE B.Efore (the) C.ommon E.ra (BCE ) Or Before Christ (BC) Or Anno Domini (AD) (translated as In the year of the Lord) 2016 + 1200 = 3215 years ago Heliocentrism - Aristarchus of Samos (310 – 230 BC) presented the first known model that placed the Sun at the center of the known universe with the Earth revolving around it heliocentrism attracted little attention — possibly because of the loss of scientific works of the Hellenistic Era—until Copernicus Tyco Brahe - Wanted to determine how the heavens were constructed and pursued a project to identify positions of both stars and planets Johannes Kepler - Best known for developing laws of planetary motion. Based on the observations of Tycho Brahe Galileo Galilei - Legend of the Leaning Tower of Pisa: Galileo showed that dropped objects fall to the ground at the same time when air resistance is negligible The Universal Law of Gravity Newton’s Law of Universal Gravitation - All objects in the universe attra
