In an accelerating or quickly braking vehicle, how is that a fly ( in the vehicle and in the air) does not slam into the sides of the vehicle's interior?  

Let's assume there's no treadmills involved.

Air mass gets moved too, brah. It's not a vacuum within.

Isn't the air inside the vehicle being accelerated at the same rate as the rest of the vehicle?

Not an engineer/physicist, but I would imagine it is because there is no force being exerted on the fly.

They have their own propulsion system with onboard guidance.  And how do you know that they don't slam into things anyways?

It is mostly closed system where everything moves at the speed of the system...same reason why the fly doesn't get squished in an airplane moving at 500 miles an hour

at steady speed this is true, while accelerating or braking it's not, that's why we feel g forces when landing or taking off in a plane

answer is air resistance.



Take a small pebble the size of a fly and toss it.  It'll go a far piece.



Take a dead fly and toss it, it'll go about 12 inches maybe

The momentum change is virtually insignificant and the fly can easily handle it as the air is also moving within the vehicle.

What if the car was on a treadmill?

The wind resistance compared to the weight of the fly is pretty high.

The wind resistance compared to the weight of you is not so high.


The fly will accelerate or decelerate some, but wind resistance will dampen it hugely.

House flies accelerate at 2 g's.   Your car does not even come close.

You're stopping slow enough to allow the fly to push back against the air with its wings.  Stop fast enough (like hit an immovable wall at 100 mph) and the fly would splat.

I read years ago that the cause of 50%  of the unexplained fatal single vehicle accidents are due to a bee or fly flying in drivers face and causing distractions.   The driver wrecks the car and the fly or bee just flys off oblivious.

and the car was inside the cargo hold of a C-130....<wait for it>
THAT WAS ON A TREADMILL

this, if this was in a vacuum the fly would have nothing to cushion the slowing of the vehichle, and slam into the glass in the front of the car.

Edit:

This video applys, just a different concept, worth the watch.

You know what'll really bake your noodle? A helium balloon. Take one along for a ride, floating in midair inside the car. Accelerate, brake, and turn, and report back how it moves.

No, surprisingly it moves around quite a bit, and not like you would think.
