The way I understand it, Galileo was the first one to use one of
Leeuwenhoek's new-fangled "telescope" things to look at
astronomical objects. Fortunately for Galileo, his telescope was
so poor that he didn't instantly blind himself when he looked at the
sun with it. He had a lot of fun looking at craters and mountains
on the moon, and when he turned it toward the planets, it was
good enough to let him see the four brightest moons of Jupiter.
(You can see them too, with only binoculars.)
This was the first time that anybody ever saw anything in the sky
orbiting anything else but the Earth. He soon realized that if those
little things could orbit Jupiter, then anything could orbit anything,
and the Earth didn't need to be the center of the universe.
When he started telling other people about this, he got into big trouble.

La olla es de metal por que se calienta mas rápido, y las manijas son de madera por que así no se calientas y tienden a estar mas frías.

Answer from: Quest

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.
