How do molecules in the air cause air resistance?

Question

anonymous · Answer

Well think of air molecules of a ball and you should know the faster you are traveling the more air resistance is going to act upon you. If I lauch a air molecule at 60 mph in air, it's going to push away all other air molecules. This will cause the "other" air molecule to hit the launched molecule causing it to slow down and eventually slow down. This is called friction or in this case simple air resistance. Hope this helps

By bumping into the object experiencing the air resistance, basically.
For instance, imagine a ball moving at a certain speed. It bumps into the air molecules, exerting a certain force on them. The reaction force of the air molecules is what slows down the ball. As you can imagine, this force is rather small for each air molecule, but combined they are significant.
