If I am the same distance from the steering wheel for the entire acceleration, my rate of change in position is zero. Therefore, my velocity is zero, which means my rate of change of velocity is zero, which means that my acceleration is zero.

The seat is what allows me to accelerate at the same rate as the car, therefore, relative to me, the car is not moving.

You seem to not understand basic physics.

You are not moving relative to the car, indeed. But that does not mean that the car does not accelerate relative to you.
The fact that you are pushed into your seat is proof that the car actually DOES accelerate relative to you.
Originally you have no speed at all; when the car accelerates and takes you along with it, it's not you who's accelerating at exactly the same pace.

You are pushed into your seat. You however, remain in position, because the seat exercises normal force to counter that pushing, to prevent you from going through.

Therefore, it is the seat that keeps you in your position; if the seat were not there, but rather an open end behind you, you would probably fall out of the car, if it's acceleration were enough. (Only with lower acceleration could you stay in the car because you would still keep contact with the floor; friction)

It is not so that you accelerate along with the car out of nowhere; u need the normal force of the seat to make you do that.
Therefore, the acceleration of the car IS relative to you, it's just that there's another force helping you stay into position.

In oder for the car to accelerate relative to me, it's distance from me must be increasing. However, I can still reach the steering wheel. How does that happen?

If I am the one who doesn't understand basic physics, please, by all means, show me with some math or equations how it is possible that the distance between me and the steering wheel doesn't increase yet it is accelerating relative to me.

That is true. The seat is what allows you to accelerate at the same rate as the car. Therefore, your acceleration relative to the car is zero. However, your acceleration relative to the ground is the same as the car's.

Exactly, you stay in position. Show me with the equations of motion how an object that maintains position accelerates with respect to that stationary position.

Because I can show you with the equations that the acceleration is zero.

*sigh*

Truly you do not understand. Try to see things apart from each other for once.
As I said above, picture yourself in a car with nothing behind you. What happens if the car accelerates quickly? You fall out. Tell me that is not accelerating relative to yourself.

Then, put the seat in place. It stops you from falling out. Does that make the car accelerate any less relative to you? NO.
It means that ANOTHER FORCE is stopping you from MOVING relative to the car.

Truly, if you cannot understand this, there is no hope for you.

You can't truely be this dumb.

If you stand on a platform with nothing to hold on to and it starts to accelerate, due to your inertia, you will not accelerate with it. You will fall off the back of it as its distance from you increases. Relative to the ground, you have no acceleration, but relative to the platform, it is accelerating from you.
Now, immagine you are strapped to it. It then begins to accelerate. The straps prevent you from moving away from the platform. Your distance from the platform is not increasing, therefore, your acceleration relative to the platform is zero. Relative to the ground, your acceleration is the same as the platform.

I still want to see those equations, because I have mine ready.

xel you must be thinking of something else. Perhaps force?

I think your problem lies with the definition of acceleration.
If you consider acceleration as actually MOVING relative to another object, instead of just applying force to (which I consider appropriate in this case),
then I think the problem of our disagreement lies there.
I tried to make it clear I consider those verbs different.

TBH I think your problem lies with misunderstanding the definition of acceleration. Besides - if you're talking about a different thing, what relevance would it have to the topic?

There is only one definintion of acceleration. It is the rate of change in velocity over time, which is the rate of change in position over time.
Applying a force causes an acceleration, but in a car, the car itself is providing the force to accelerate your body. If your change in position does not change in the car, how can you possibly be accelerating with respect to the car?

the definition of acceleration is not necessarily a change in position; it is merely a rate of change over time. It doesn't have to be used to define position, merely change. What change is arbitrary.

Ok, maybe you are that stupid.

Answer this:
I have a ice maker in my fridge, which produces 16 cubes an hour. What is the acceleration of my fridge with respect to the moon?

The change in what is not arbitraty. There is only one definition of acceleration.

There's more than one definition, and most are quite general too.
Though it could ofcourse differ per dictionary.

Funny how you just completely ignored what Negata asked, but then again you're calling people stupid at the same time.

Exactly what I thought, you all seek for farfetched explanations why the earth is flat. While it is much easier and plausible to believe the earth is round. I'm yet to hear a logic explanation why the earth isn't round.
