Does a 200mph wind have the same force as moving 200mph into still air?

what wind has more force the wind of you standing on top of a car doing 200mph or you standing still and a 200mph wind hitting you?

In both cases, the wind feels the same on your skin, so it is hitting you with the same force.
 
i want to add to my question to get further answers. the question started when my friend said he has been in 100mph winds. being he exaggerates often i said you probably haven't been in 100mph. He said yes I have, i drove 100mph on my motorcycle.
 
Ah, yes, the feeling of 100mph wind on your face is indeed the same wether you're riding your hog in sunny weather, or holding on for dear life in a storm.

Huh? Windscreen? No, I was talking about only the feeling on your face. The rest of the body, windscreen or no, is irrelevant. In any cast, problem solved, so let's lock it up. :smile:

I wear a full face helmet, (also ear plugs to reduce wind noise), when I ride a motorcycle. Considering head height is almost as high as a SUV, speeds on a motorcycle appear to be lower than in a car. 100mph or faster wouldn't be too fun if your face was exposed.

Well, the point is that the air in the envelope of a moving motorcycle, even where your face is, is possibly significantly less than 100mph relative to you.

A 100mph wind OTOH, would be truly 100mph.

True, but this is negligible and I don't think it's the question being addressed.

I don't think it is negligible, and I do think it's the question being addressed, as per post #3, in which the OP explains the circumstances under which the question has been raised.
