difficult physics for me to comprehend please help

[Marty Champions]

Haven't read the thread, but I guess I entered the fray too late:

The ball travels at the same speed/direction as the airplane hence it will carry a speed vector of the same magnitude as the airplane.

This illustrates your problem

The larger rigid coordinate system could be Earth, while the moving system is the plane. While inside the moving coordinate system, you will not detect any speed you carry relative to the fixed system. This is why we do not detect that we travel thousands of miles per hour as the Earth spins around its axis and around the sun. This is also why the ball will move in the direction you throw it in while inside a speeding plane.

a vector is a plot on graph , but there still exists the vector of the free space before the train entered it

None of us are connecting the deeper reasoning

Oooh, I've got a good one.  Say you unwire a lathe's electrical box and remove upwards of 30 wires.  Naturally you label each one with a little tag and then you write a corresponding code on the little brass clamps on the electrical board.  Now you know where everything goes back again.

So in order to ensure it was wired right to begin with you take the now demounted circuit board (circa 1943) inside and decide to map the board with the multimeter.  But it's a pretty greasy affair so instead of letting 70 years of grease interfere with the mutimeter giving a true read you realize this is the perfect time to unwrap the new can of contact cleaner that's been waiting in the shed.

So you degrease the board and sit down to map it out.  And it's a good thing you're going to map it out and come to a full understanding of exactly why things were wired as they were because now there's none of your codes remaining on the brass clamps anymore since the contact cleaner washed them all away.

So on a scale of 1-10, how big of an idiot would someone have to be to do this?  Just hypothetically.

yes not bright to erase wire references when trying to "discover "more, you just created a shitload more workmore work on the bright side u got an oppurtunity for deeper understanding.to learn wher the wires go.. bu am i missing something .. is it even possible to find the proper destination of the wires now?

[Bam-bam]

Why is it that if i have a jar with a seed in it and do a throwing motion we all know that the seed would rattle around at the speed i moved my hand , now.....
What about a huge airplain  goin 300mphwith a passenger tossing a baseball up, why doest the baseball hit the back of the plane at 300mph

Its the same scenario but different results

No, the vector contains the information of the object you investigate. In this case, the vector contains the information of the object's velocity and position. Earth is the fixed coordinate system, which yeilds the planes velocity (relative to earth) and the plane is the moving coordinate system. At the same time, when you throw an object inside the plane, the plane becomes the fixed coordinate system, while the thrown object assumes the moving coordinate system.

ok say if greg plitt was hanging from a tree just above the train where his leggs enter through a top slit in the train with the train going 150mph , lets say the train is 2  miles log gregs legs are then not  accelerated but hit back of traineventually
But Gregs legs as you say are in the coordinate system of the train

[doison]

Acceleration.
This is even cooler, it is theory that the fastest you can go is the speed of light, but a train were invented that could go the speed of light and you were inside and threw a ball, would it move?

How are you gonna move your arm forward to throw it?

[FermiDirac]

You should view the different coordinate systems as a means of keeping track of relative movement. Thus the legs could be given a third coordinate system, which moves relative to both the coordinate system of the train as well as the "fixed" coordinate system of the Earth/tree/body.

exactly!.and cells won't move so you should in theory not move or age one bit.

[Tapeworm]

is it even possible to find the proper destination of the wires now?

Hypothetically.


I think you'd enjoy this antique circuitry greatly, my electromagnetic amigo.  Copper and brass contacts abound.  So pretty.  And the sheathing on the wires looks to be some sort of cotton weave.  I was going to replace the long runs of wire until I discovered they're all cloth covered.  Guess that's how they used to make wire on the plantation.
