Copernicus's heliocentric model and ptolemy's geocentric model were each developed to provide a description of the solar system. both models had advantages that made each an acceptable explanation for motions in the solar system during their time.
sort each statement according to whether it is an advantage of the heliocentric model, the geocentric model, or both.
drag the appropriate items to their respective bins.
planetary orbits and motions based on greek ideologies of perfect form and motion
predicted planetary positions accurately over relatively short time periods
explained planetary motions and brightness changes most simply
rooted in widely accepted religious beliefs regarding earth's place in the universe
a) heliocentric:
b) geocentric:
c) both geocentric and heliocentric:

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

Ithink the answer would be 1,350!
