Does Aristotle's model differ from others?
Yes, Aristotle's model of the universe does differ from other models, such as the Ptolemaic or Copernican systems. Aristotle proposed that the Earth was the center of the universe and surrounded by concentric spheres, with the outermost sphere containing the fixed stars. This geocentric model was later replaced by heliocentric models proposed by Copernicus and Galileo.
Why models of the ealry ptolemy solar system were replaced by the copernican model?
The early Ptolemaic model placed Earth at the center of the solar system, which led to complex explanations for retrograde motion of planets. The Copernican model shifted the center to the Sun, providing a simpler explanation for planetary movements. Additionally, the Copernican model was supported by observational evidence and eventually gained wider acceptance due to its better predictive power.
How do the phases of Venus's help?
Galileo was able to observe Venus going through a full set of phases, something prohibited by the Ptolemaic system (which would never allow Venus to be fully lit from the perspective of the Earth or more than semi-circular). This observation essentially ruled out the Ptolemaic system, and was compatible only with the Copernican system and the Tychonic system and other geoheliocentric models such as the Capellan and Riccioli's extended Capellan model.
How did Nickolaus Copernicus account for the retrograde motion of the planets?
The retrograde motion of the planets is well modelled by both the Ptolemaic system and the Copernican system, and by the other models. But the Copernican system explains it more simply because, for example, Mars's retrograde motion is caused simply when Mars is overtaken by the Earth, which goes more quickly round the Sun. Thus an observer on the Earth sees Mars appearing to go 'backwards' on the ecliptic around the time of closest approach (opposition). This can be easily demonstrated by assuming simple circular orbits.
What are models called with earth in the center of the solar system?
'Out-dated' or 'pre-Copernican'. See the related link below, please:
What was a major flaw of the Ptolemaic model?
A major flaw of the Ptolemaic model was its complexity in explaining the retrograde motion of planets. Ptolemy introduced the concept of epicycles and deferents to account for this, which made the model overly complicated and not as accurate as later models, such as the heliocentric model proposed by Copernicus.
How was nicholas Copernicus research proven by Johannes Kepler?
Kepler's theory eventually replaced Copernicus's theory after Tycho Brahe's measurements enabled Kepler to realise that the planets move in elliptical orbits and not in the circles and epicycles of the older Ptolemaic and Copernican models. Copernicus was able to simplify the older model by placing the Sun at the centre instead of the Earth. Kepler in his new theory of 1609 retained Copernicus's idea of placing the Sun at the centre.
How did Galileo 's observation of Jupiter and Venus support Copernicus' model?
Galileo's discoveries with the telescope sowed doubts about the ancient Ptolemaic model which had the Earth at the centre. First, Jupiter's moons orbited round Jupiter and not the Earth, the first objects that had been discovered that were not orbiting the Earth. Secondly the discovery of the phases of Venus raised doubt about the Ptolemaic model, particularly the gibbous phase when, we now know, Venus is round behind the Sun as seen from Earth. In the Ptolemaic model Venus never goes behindthe Sun (as seen from Earth) and the gibbous phase cannot happen.By implying in the title of his book 'Dialogue of the two world systems' that there were only two models in contention, those of Ptolemy and Copernicus, Galielo insinuated that if the Ptolemaic model was incorrect the Copernican system must be correct. This was logically flawed because at the time there were two other systems in the public domain that both explained Venus's phases. These were the models of Tycho, which was geocentric, and finally Kepler's which was heliocentric.Of these four, Kepler's was eventually accepted by everyone after Newton's theoretical discoveries showed that Kepler's elliptical orbits for the planets agreed with the new theory of dynamics.
How do you replace opel cv joints?
That depends which model it is. On older models CV-joints were moulded into the driveshaft. To be replaced they had to be removed using a press and then warmed to be able to replace them. On these models it is often better to replace the whole driveshaft. On newer models CV-joints are attached with clips and can be replaced more easily.
How do I replace a 2005 Ford Mustang belt?
* To replace the belt rotate the tensioner counterclockwise on V6 models or clockwise on V8 models to relieve the tension on the belt * Remove the belt from the auxiliary components
Why do scientists not accept the ptolemaic model?
The Ptolemaic model is also known as the geocentric model, where the Earth is at the center of the solar system. Scientists refute this because orbital paths show that the solar system is heliocentric.
Will this be easy to replace my old fan with?
Nu-tone series is almost universal to most models so its easy to replace
