Gallileo and His NATURAL FALL DOWN LAW
M----------Earth
m
Mass M and m will natural fall down in one and the same time
Marosz my sentense more to Gallileo
M----------Earth >>>
m
natural fall down time has strong relation with constant motion
and inverse Square low ( important is from where Earth started wave
************************************
m-----Earth-----m >>> motion
mass m left and mass m right will not touch the Earth in one and the same time ( motion !!!)
HISTORY - SIMILAR PARAGRAPH RIGTH NOW WE HAVE IN BOOKS
" 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
MAROSZ
Gravitation or Light it is the apparatuses that they can use
one of the cornerstones of Einstein's theories of relativity
is already not actual !!!
