Think your SMART!!??
then figure this question...
if you are in your civic HB with a h22 inside it and your flying down the highway at 230km/h (407) and there is a fly in your car flying.
Is that fly, flying at 230km/h???
why or why not?
...
...
...
...
Also if you stop your car(slame the brakes) withh the flying fly hit the windshield????
hahhahahaha......

Hope its not this orange civic your driving...
HMMMMMMM...
Very similar to the "Why if I jump in a airplane aisle while the plane is flying doesn't the back of the plane smack me in the ***?" question.
Try it sometime....
You can be the fly...
Post your experiences here..

(I) Newton's first law, in its correct form, is the law of momentum:
momentum = mass * velocity
(II) Inertial frames of reference (curtousy of Einstein) claim that an object's speed (the numerical value of it's velocity) can be compared to any reference point:
if you run a stop sign at 40km/h, you'll see the sign wizz by you at 40 km/h
(III) Engineers use Newton's law of momentum to gauge speed (velocity) for cars, air planes, space ships, you name it - because it eliminates the need for a reference point:
In summary, your speed can be measured by how much force (force*time = momentum for those keeping track) it would take to bring that mass's velocity down to zero - or place the object at rest.
Knowing this, here are my straight answers to the questions:
Yes, the fly is flying at 230km/h, and
Yes, it will smoke the windshield because nothing else can slow it down.

wut about inertia ,an object will stay in motion unless another object of equal matter stops it.........so , if u hit u r breaks, the fly will deffinetly hit the winshield..................................end of discussion............

however if the plane accelerates or decelerates while you're in the air then you will move either backwards or forwards relative to the floor.

i'll have to disagree with that one. in order for you to gauge velocity there MUST be a reference point. the term velocity is meaningless without a reference point. the whole notion of momentum revolves around having a reference point.

The fly would be minding it's own business then get hit with a mean ol' windshield. Actually, since a fly is so small I think it works a little differenet in terms of the physics. Air is a thicker fluid for the fly. It may be that as the car decelerates, the pressure from the back of the cabin will push the fly forward (into the windshield), or just cause the fly to feel some turbulence.

Isnt the speed of the object (the fly) relative to its environment.??
The fly is in another environment (which is the car).
therefore the car is moving at 230km/h and the fly is Travelling at 230km/h. But its not flying at 230kkm/h. Its flying at is own velocity whichin the vehicles atmosphere. In turn the vehicle is moving at 230km/h and so is its atmosphere. But the fly flying in the cars atmosphere is flying at its on pace.
Its hard to explain.
Think of it as the world is spinning and were on the world moving at our own pace within the worlds atmosphere.
confused yet? haha

Damn I hear this from my Girlfriend all the time cause shes in engineering, funny its on this forum. Since we're talking about smarts, the use of the word "your" was not properly spelt in the context in which it had been used. Ex: "and your flying down the highway" The proper spelling should be "you're". Correct my if Im wrong. Probably not. :P
Look at Eithstiens Theory of Relativity...he'll tell ya.

it's all about the threoy of relativity .... if your looking at the fly's speed realitive to ground then yes that fly is booking it... if your looking at it fly speed realitive to car speed the fly is just a fly

- yes the fly is traveling at 230km/h not under it's own power, however it is traveling at that speed due to the car
- yes it would hit the windsheild if you could slow down fast enough
and in terms of
as the car decelerates there is no movement of air from the back of the cabin towards the windsheild... where would this air be going? out the windsheild? it just may be that because the fly is so light and the air inside the car is decelerating along with the car the fly doesn't slam the windsheild, you can hardly compare a human sitting in the pasenger seat to a fly that weighs next to nothign..
plus you haven't specified where the fly is... it could be in your pocket for all we know thererfore it would not hit the windsheild.
