Why are jupiter and saturn not perfectly spherical? they rotate rapidly. they have very active auroras that heat the atmospheres along the poles. they have storms that develop preferentially along their equators they formed from the collision of two large planetesimals?

They spin rapidly.

Jupiter and Saturn have equatorial bulges and appear like a squished ball. The outer edges of the equator try to keep up with its rotation and move faster than the center. The bulges are shaped as the two planets spin very quickly.

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.
