I was in past in point 1 after short time I'm in point 2
I will be in point 3 ( I no need other bodies in the universe to conirm my velocity ???)

Kinetic parabola respect to apparent point

I was in past in point 1 after short time me and rocket ...?

( please take a pencil in your hand make the same drawing and please write
old equation from secoundary school --> after You tube You will be able prepare mathematical evidence that galileo made mistake ...more detail later in post )


move up pendulum "L" distance from the Earth level

pendulum that wait for test has got velocity ? after we start pendulum potencial energy will be change for kinetic energy . ( please back in Your mind to my first Ytube )

Parabola and Delta Y ( kinetic energy ) and Delta X ( velocity change ) ???

Can we measure different velocity ? Please study below You tube
Please ask Your self what about perpendicular direction to train velocity ? do we have ideal symetry ?

What about above test right now we can read in books
please read all ( I mark red colour problem that you can solve
-- my first Ytube and secoundary school equation but respect to stationary virual apparent point )

" Galileo postulated his relativity hypothesis: any two observers moving at constant speed and direction with respect to one another will obtain the same results for all mechanical experiments (it is understood that the apparatuses they use for these experiments move with them).
This idea has a very important consequence: velocity is not absolute. This means that velocity can only be measured in reference to some object(s), and that the result of this measurment changes if we decide to measure the velocity with respect to a diferent refernce point(s). Imagine an observer traveling inside a windowless spaceship moving away from the sun at constant velocity. Galileo asserted that there are no mechanical experiments that can be made inside the rocket that will tell the occupants that the rocket is moving .
The question ``are we moving'' has no meaning unless we specify a reference frame (are we moving with respect to that star'' is meaningful). This fact, formulated in the 1600's remains very true today and is one of the cornerstones of Einstein's theories of relativity."

Montion respect to appaarent point

Vo = 2 m/s

Ek = 2 joules

You want to change mass m speed form 2 m/s to 0 m/s ( please use E =2 joules)

You want to change mass m speed form 2 m/s to 4 m/s ( please use E =6 joules)

0 m/s ------------2m/s ------------4m/s

Water flows from mountain to sea level we can not change it
Energy always escape more easy there where is more Easy way to escape ( optimal direction we can measure and confirm from inside our own coordination system )

my last picture explain symetry and asymetry situation

Gallileo made mistake we have absolute space and time
