thanks a lot now i understand what did u mean

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?

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

so, from ur explanation A and B wins and reach at the same time? :confused:

thanks for all .. but i need the right answr today please?? A or B wins the race? and why?? Dadface: can u answer ur question "If there is no energy loss what does that tell you?"

at the same time?:confused:

http://up2.up-images.com/up//uploads2/images/hosting-036ee42f15.jpg in the figure, which ball will win in the race? note: there is no energy loss

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? http://up2.up-images.com/up//uploads2/images/hosting-1067f93ac6.jpg
