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 60C^o and the other with 30C^o, which one will reach first?

What do you think?

at the same time?

 

[xxChrisxx]

Why do you say that?

Think about equations for air density and air resistance.

 

[sa_ta]

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

This isn't how it works on the forums, we don't just give you the answers to homework questions because you won't learn anything.

I'll direct you to the answer.

Air resistance (drag) : http://en.wikipedia.org/wiki/Drag_equation
Density of air : http://en.wikipedia.org/wiki/Density_of_air

look at those equations, and think about what you know.
hint: the air density eq can be fitted into the drag eq.

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?
