have you ever wondered about this phenomenon?

The fly is circling around relative to its surroundings. Its the same as asking if you move your hand forward in a car going 80 miles and hour and your hand moves forward one foot in two seconds, why is it not breaking through the front window?
Relative to its surroundings, is is only moving one foot in two seconds.

It does not hit the windshield for the same reason you don't. When a car moves, not only is it moving but everything inside it is moving. So the fly is really moving at 80 mph along with the car, and so are you. However if the car suddenly stopped going 80 mph, the fly would continue to go 80 mph and hit the windshield, as it would be moving faster then the car.

Yeah that's a good question. It's all about relative motion. Driving 80 mph, the driver is actually moving forward at 80 mph as well as any object in the car. You toss a ball straight up in the air, it moves at 80 mph. If you throw it at the back window of the car at 10 mph, it's now actually travelling at 70 mph though relative motion in the car is only 10 mph. Likewise if you throw it at the windshield at 10 mph, it's now moving at 90mph. It's all about relative motion. All of this applies to the fly. Great question. Hope this helps

Whenever you talk about velocity, you have to talk about it with respect to something. The fly moves in a circle at a speed of 10 mph with respect to the air, and the air inside the car moves at 80 mph with respect to the earth, as does the car. Since the fly is moving back and forth with respect to the car (and its windshield) there is no reason for it to smash up against the window.
If it were outside where the air is basically not moving with respect to the earth, it would get smashed against the windsheild.

The air inside the car is also travelling at 80 mph.

phenomenon? you need to look up that word. the car is going 80 not the fly, everything in the car including your self is at the same speed so why arent you asking why humans are not mashed up the window?

we don't understand, who ? the linked fee decrease develop into 55 mph decrease back interior the 1980's, while romney did it 2. So i assume your against horse trailors to, in view that they are pulled at the back of a truck ? 3. And farm animals automobiles on trains ?

it's because the flight speed of the fly is partially associated with teh air flow, the interior air of the car is usually either non circulatory or just slighlty more in motion that completely still air. Thus as far as the fly is concerned it's sitting still....Now open a window...and whooosh the fly gets sucked out...

The air in the car is stagnet to the fly.
Meaning tha the car carries the air in it with it. So the fly, flying in the air in the car is being 'carried' along by the air.
It is like having a fish in a fish tank when the car is moving. Does the fish have to be swimming at 80mph to be in the tank? No right?

Read relative motion, and then compare it to G-force.
If the car is driving at 80 mpg then everything it contains is also. Now hit the brakes! SPPLLAAATTTT!!!! Bye fly, bye human, bye Serial Killer in the back seat...
