4. What force holds the planets in their orbits?GRAVITY!
Newton!
5. Who developed the theory of gravity when he (supposedly) saw an apple fall from a tree?
Who To Believe?Prior to the 1500’s most beliefs were founded
on one of two sources:Ancient Greeks or Romans The Bible or Church
What is the Scientific Revolution?A new way of thinking about the natural
worldBased on:
Careful observationWillingness to question status quo
Age of Exploration exposed Europeans to new people and new ideas
Also led to discoveries in astronomy and mathematics
Where on Earth?Aristotle believed that Earth was the center
of the universeGeocentric Theory
Belief that the Earth was the center of the universe was supported by the Church
CopernicusNicolaus CopernicusHeliocentric Theory
Studied movements of the planets for 25 years
Concluded that the sun is the center of the universe

Jupiter has 4 moonsMoon has rough, uneven
surfaceSun is center of universe
Just kiddingPope summons Galileo to
Rome to defend his theoriesMade to stand trial before the
InquisitionUnder threat of torture,
Galileo renounces Copernicus’ theory (and therefore his own)
Lived under house arrest for the rest of his life
Scientific MethodLogical procedure for gathering and testing
ideasStart with a problem or question from an
observationForm a hypothesisTest hypothesisAnalyze/interpret the dataEither confirm or disprove hypothesis
Two approachesFrancis Bacon
Encouraged to experiment then conclude
Rene DescartesUse mathematics and logicAssume nothing
What goes up, must come downSir Isaac Newton
English mathematician/physicist All physical objects affected
equally by the same forcesSame force ruled motions of the
planets and all matter on earthEstablishes the law of gravity
