The Ptolemiac model was able to explain retrograde movement by having the planets move on smaller sized circles attached come the bigger circles on which they went around Earth.
You are watching: How did the ptolemaic model explain the apparent retrograde motion of the planets
-Science progresses v the creation and also testing the models of nature that describe the observations as merely as possible.--Modern scientific research seeks explanations for observed phenomena the rely exclusively on herbal causes.---Models should make testable predictions the will pressure us to review or give up the model if they execute not agree through observations.
At most times, Mars appears to move __________ family member to the stars. The exceptions are during its periods of apparent retrograde motion, when Mars appears to relocate __________ relative to the stars.
If you want to document the apparent retrograde motion of Mars, girlfriend would must measure and also record Mars"s.... End a duration of_________ returned
What is really happening in an are during the periods as soon as we watch Mars walking through evident retrograde motion?
Consider a time as soon as Mars is in the center of among its periods of obvious retrograde motion. Throughout this time, Mars appears _____ in our night sky and also crosses the meridian roughly _____.brightest; midnight
The Sun-centered system pictured in the lower window of the video offers a straightforward explanation for observations of obvious retrograde motion. Have to these truth alone have been enough to convince the ancient Greeks that planet really go go roughly the Sun?
No, due to the fact that the Greeks had an Earth centered model that also accounted for apparent retrograde motion.
observe planetary location with adequate accuracy so that Kepler could later use the data to discover the legislations of planetary motion
making observations and conducting experiments that dispelled scientific objections to the Sun-centered model.
Based on the video, i beg your pardon Venus phase would certainly be impossible to view (from Earth) if Venus orbited planet as described in Ptolemy"s Earth-centered model?
1. Venus sometimes shines brightly in the west sky quickly after sunset2. Venus sometimes shines brightly in the eastern skies shortly prior to dawn
In Ptolemy"s Earth-centered model, as soon as would Venus appear directly behind the sunlight as perceived from Earth?
As girlfriend learned in the video, Galileo"s monitorings of Venus in gibbous (nearly full) phase showed conclusively that Venus orbits the Sun, not Earth. Which figure shows Venus"s position once Galileo witnessed it in gibbous phase?
The video states that the planetary orbits are shown to scale. I m sorry statement correctly explains the way the planet sizes space shown contrasted to their orbits?
Kepler"s very first law says that the orbit that each earth is an ellipse through the sun at one focus. I beg your pardon of the following statements describe a properties of the solar mechanism that is explained by Kepler"s first law?
---The sunlight is situated slightly off-center from the middle of each planet"s orbit.--Earth is contempt closer to the sun on one next of the orbit than on the other side.
Kepler"s second law says that as a world orbits the Sun, that sweeps the end equal areas in equal times. I beg your pardon of the complying with statements define a properties of the solar system that is defined by Kepler"s second law?
Kepler"s 3rd law says that a planet"s orbital period, p, is regarded its mean (semimajor axis) orbit distance, a, follow to the mathematical partnership p2=a3. I m sorry of the following statements explain a characteristics of the solar system that is explained by Kepler"s 3rd law?
--Inner planets orbit the sun at greater speed than outer planets.--Venus orbits the Sun quicker than earth orbits the Sun.

The mathematical kind of Kepler"s 3rd law actions the period in years and the ______ in astronomical units (AU).
According come Kepler"s second law, Pluto will certainly be traveling fastest roughly the Sun once at ______.The level to i beg your pardon Mar"s orbit differs from a perfect one is ______.eccentricity
