1what were the two classifications of motion, according to aristotle? a 2 according to aristotle, what kinds of motion required no forces? a 3 what simple way of interpreting astronomical observations did copernicus advocate?

1. Answer;

Natural motion and violent motion

Explanation;

-Natural motion is the motion arising from the nature of an object. This motion does not require an external cause in order to occur. For example: Heavy bodies naturally move toward the center of the earth, therefore falling is a natural motion.

- Natural motion was determined by the nature of the object and how much of the four classical elements it contained. Violent motion is caused by external forces applied to the object.

2. Answer;

Natural motion

Explanation;

Natural motions are those motions that objects naturally did: objects on earth fell towards the center of the earth. Heavenly objects naturally moved in circles. Additionally, heavy bodies naturally move toward the center of the earth, therefore falling is a natural motion. The natural motion of objects is one of the characteristics of an object.

3. Answer;

To assume that Earth and the other planets rotate around the sun

Explanation;

-Copernicus proposed an alternative theory--that the Earth was a planet orbiting the Sun, and that all planets moved in circles, one inside the other. Mercury and Venus had the smallest circles, smaller than that of the Earth, and therefore their position in the sky was always near the Sun's.

-That made it easy to estimate their distances from the Sun in terms of the Earth-Sun distance.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
