1.4 Flashcards
What was the relationship between Kepler and Tycho, Copernicus and Galileo
Kepler discovered Tyco’s observations and discovered three laws of planetary motion
Copernicus and Galileo both believe in the heliocentric theory
Explain Kepler’s first law
The planets orbit the sun in ellipses with the sun at one focus
Explain keplers second law
the line joining the sun and a planet sweeps through equal areas in equal times
What did keplers second law replace
the universal rate of revolution
Relate the second law to halleys comet
Within months through the inner part of the solar system, it takes the rest of its 76-year period moving slowly through outer parts
explain keplers third law
the square of the period of revolution is proportional to the cube of the seminator axis of the ellipse
What is the representative equation for the third law
P^2planet/P^Earth=R^3Planet/R^3Earth
What else will confirm to the third law
Artificial satellite in orbit around the earth and to the moons of other planets
who was the first to use a telescope
galileo
give 3 things that he saw or discoveries that he made
Milky Way contained individual stars

who was thought to be omniscient? How did gelileos findings affect that belief
Anstotte
Ptolemy
Proved all bodies did not revolve around earth
How were newtons laws different from keplers
newtons laws was broken down into a spectrum and his invention of reflecting telescope
who invented calculus
newton
what did newton discover about gravity
that the same law that describes how objects fall on earth describes how objects more far out in space
