Question

why does air resistance act upward?

Answer 1

Friction opposes the motion of an object moving through/on a medium. In this case, the air is opposing the motion of something moving through it. Air resistance only acts upward, opposing direction, for an object moving downward. A skydiver feels air resistance acting upward, a rocket feels downward air resistance.

Answer 2

Answer:

Friction opposes the motion of an object moving through/on a medium. In this case, the air is opposing the motion of something moving through it. Air resistance only acts upward, opposing direction, for an object moving downward. A skydiver feels air resistance acting upward, a rocket feels downward air resistance. force of air resistance acts opposite the direction of gravity (upward).
