안녕하세요!

1) think about the relationship between Area and Force.

Pressure = Area x Force.

if you want to maintain the same pressure, but start decreasing the area,

logically, you need to increase force.

air resistance is air pressure pushing you against the direction you want to move.

if you reduce the amount of area this air resistance can act upon you,

there needs to be an increase in force in order to achieve the same pressure.

this force is dependent on how strongly you push against the air molecules, 

which is the same thing as saying it's dependent on how fast you are moving.

therefore, you have to travel faster until the air resistance and acceleration can cancel each other out,

resulting in a faster terminal velocity.

2)  이건 우리가 newtonian physics보면서 했던 내용이여서 다시 한번 복습해보는게 좋을것 같은데요

그냥 간단하게만 말하면 air resistance always depends on the movement of the object

if the object doesn't move, there is no air resistance.

if the object moves faster and faster, there is greater and greater air resistance.

air resistance can get so big, to the point where it cancels out acceleration due to gravity

allowing the object to stay at terminal velocity.

but to get to that point to begin with, the object needs to move very fast.

if the object doesn't move that fast, it doesn't have that great of air resistance,

meaning it cannot cancel out acceleration due to gravity.

물리학은 공부하면 할수록 어렵다가, 어느 순간에 갑자기 깨달음(?)을 얻게 되면서

엄청 쉬워지는 경우도 있으니, 머리속에서 배운 이론이랑 현실세계에서 내가 보는것들 연관성을 잘 파악해보면서 조금만 더 힘내요!  :D
