Homework Statement
Some disease-causing bacteria are carried by the air. Why don't these organisms fall to the ground as other objects?
Homework Equations
Drag equation might be useful here (I think)
The Attempt at a Solution
I think it is because of air resistance. It is the force that are in opposition to the relative motion of an object moving through the air. It depends on velocity. It is calculated by using the drag equation.
However, I couldn't really figure out the connection between these.
