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.

Both geocentric and heliocentric:

Explanation:

In the configuration of the geocentric model, the Earth is in the center and the other planets and the Sun rotates around it in a circular motion.

On the other hand, in the configuration of the heliocentric model the Sun is at the center with the planets and the Earth in circular orbits around it.

The geocentric model had more acceptance by the civilization of the epoch since it was able to share the beliefs of perfect motion in the most perfect shape (which were circles for them) and with the Earth in the center of the Universe.

However, by centering the Sun, the heliocentric model was able to explain the motion of the planets in a more simple way. For example, the retrograde motion.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
