Question

Why doesnt a fly get smashed against the back window when inside a car traveling 60 miles per hour?

Answer 1

For the same reason as when your pet dog jumps up on the back seat - he doesn't get thrown backwards. They are travelling at the same speed as the car .

Answer 2

It is a simple. It is traveling at the same speed as the car and there are no other forces to trow it at the window. Try trowing a small ball out the window while moving. You will see for a split second the ball stays with the car. Then slowly arcs down and away as the air and gravity take it.

Answer 3

If a fly enters a running car @ 60 miles/Hr, it might get smashed. practically, it cannot enter the car at that speed.

So it is with in the car, and catches the momentum of the car, and remains within. keeps flying, and bothers you.

Answer 4

Because the insect is constantly moving along with the air that surrounds it.

Answer 5

The essential concept that you should try to understand is that velocity is "relative". That means that there is no absolute velocity in the universe, and it is only meaningful to specify the velocity of one object relative to another. All the laws of physics are the same in any reference frame moving at constant velocity, so there is no way in principle that you can tell  whether you are moving or not *relative* (there's that word again) to the ground based on observations (like of flies) confined to the interior of the car. You'd have to look out the window to even know.

Answer 6

relativity and inertia buddy...

Answer 7

Because the Fly is moving at 60 MPH with the car. Flies on the outside get smacked because they are moving at a very low speed, then a car comes along and makes contact with them. When contact is made, the fly is given alot of force over a very small amount of time to the point where the flies body can't take it, and it just splatters. Flys on the inside don't have that problem, they were inside the car when it accelerated, and the fly accelerated with the car to the point where it was moving 60 mph. The curious thing is that both the fly on the inside and the outside both had the same amount of force exerted on them, the fly on the outside had that force exerted on it in a fraction of a second, but the fly on the inside had that force exerted on him over a much longer period of time.
