How can you drop something like a phone in a car moving 100 km/ph.
Yet it does not fly back and hit the window technically you are moving away from the point it was dropped in the air at 100 km/ph, yet it falls to the floor like you were not moving at all.

Physics.

Physics.
I know it's physics it's just something I've never understood in the slightest.

You're wonderfully helpful.

Elementary my dear Watson. Because the phone is moving at the same speed as the car and wind resistance isn't pushing it back.

Really? i figured once i let it go and it was floating in the air the car itself moving would be faster than the phone in the air.

gladly it doesn't happen or imagine what would happen if you were standing on a bus

Oh god..

It's a simple thing called momentum.

When you travel inside a contained object it creates a pocket unaffected by the outside forces. For example:

The reason you don't feel the speed and the phone does not react to it either is because everything inside your car is also traveling at 100kph and you are shielded from any drag due to being in an enclosed bubble inside your car.

The force is pushing all around your car, however you are inside the envelope which is not affected by the drag and friction of the outside forces because it is shielded from that. It's the same basic principle of standing behind a piece of glass with a fan blowing on the other side. Why doesn't hair hair blow? Your hair doesn't blow because there is a piece of glass between you and the air flow.

If you were to drive a convertible car with the top down however and do the same thing, you would notice very different results.

Wow, that made me giggle.

[Piero]

Same thing that keeps you from flying back and crashing through the back window of a bus. :D

That mean if youre going at 100 on a freeway and throw something out of your car Its gonna go fast.

[Tropa]

Gravity! and hax

Yep, it's inertia. An object in motion will stay in motion unless an outside force acts upon it. There's no outside force stopping your phone (which is traveling at 100 mph) and detain it at the point you dropped it at.

[Kueh]

The same reason you don't randomly fly several miles over, or even into space, whenever you jump.

The earth = car. You = phone.

Think of it in the opposite direction. Why should the phone suddenly gain a backward force enough to make it move backward randomly just because you let go of it? Now, of course we're talking about the car moving at an unchanging speed. Try this again while the car is just starting to move (like from a red light) and you'll find out that the phone really does move backward.

This is because of exactly what you said. Once the phone drops and until it hits something else, it is its own freely moving body, and it moves with whatever forces and momentum it was given at the start. Your car is also its own body, and while the two of you move at the same speed, the phone won't really appear to move (horizontally). But if you were to drop the phone, and suddenly start speeding up, then the phone wouldn't get any of that energy since it's its own unconnected body, and would lag behind.

And on that subject, I think you should watch this video. It might shed some more light on your question, and I think it will interest you.
