modelos planetarios and leyes de kepler :

Question 1

modelo geocentrico:

Answer 1

ancient Greeks,Earth at the center of the universe, with all celestial bodies circular orbits around it. accepted until 16th century.

Question 2

modelo heliocentrico :

Answer 2

Nicolaus Copernicus in the 16th century, Sun at the center, with planets orbiting it in circular paths.

Question 3

keplers laws what do:

Answer 3

Kepler’s Laws refine the heliocentric model with greater accuracy:

Question 4

all laws:

Answer 4

First Law (Law of Ellipses): Planets follow elliptical orbits, with the Sun at one focus of the ellipse. Second Law (Law of Equal Areas): A line from the Sun to a planet (radius vector) sweeps out equal areas in equal times. This means planets move faster when closer to the Sun (perihelion) and slower when farther away (aphelion).Third Law (Law of Periods): The square of a planet’s orbital period (T, time for one complete orbit) is proportional to the cube of its average distance from the Sun (r), written as T^2=kr^3. k is a constant(for the solar system k=3*10^-19 s^2/m^3)

Question 5

talk about ellipses properties:

Answer 5

ellipse’s properties: it has two foci (the Sun is at one), a major axis (longest diameter), a minor axis (shortest diameter), and an eccentricity (weird e looking thing = c/a) c is the distance from the center to a focus, and a is the semi major axis.
