Homework Help: Does air temperature affect air resistance?

    Does air temperature affect air resistance?

    you have two similar balls, you failed them at the same time in two plate, one of them with 60Co and the other with 30Co, which one will reach first?

    at the same time??????:confused:

    Why do you say that?

    Think about equations for air density and air resistance.

    when temperature is low the density is high
    but what about air resistance?
    explain the answer directly without ask me another questions? :cry:

    thanks for ur helping
    from equations, the velocity of the object increase when temperature increase
    so, ball 1 "60C" reach before ball 2 "30C"
    is that true?
