Both ptolemy and copernicus incorrectly explained the motions and orbital paths of the planets by basing their models on greek ideologies of perfect form and motion. what were the greek ideologies forperfect form and motion? -an oval and non-uniform motion - a circle and uniform motion
-an oval and uniform motion -a circle and non-uniform motion

a circle and uniform motion

Explanation:

Ptolemy's model of the universe placed the Earth motionless in the center of  a universe subject to uniform circular motion, the other planets, the Moon and the Sun describe complicated orbits around it.

As Ptolemy was a respected astronomer and geographer, this idea was accepted for a long time, until Copernicus arrived with the new model (heliocentric theory) that placed the Sun at the center wir the Earth and other planets describing circular orbits around the star. However, the heliocentric theory did not explain why planets orbit the Sun at different speeds at different times, because this model used only circular orbits in uniform motion.  

All of this is due to the Greek ideologies of perfect form and motion with a perfect circle. But then, the astronomer Johannes Kepler refined the Copernicus' heliocentric theory with the introduction of elliptical orbits.
