Because all matter on the earth is be flung outward into space by the earth’s curved G force path of falling towards the sun, gravity on earth seems not to change as earth rotates. Astronauts on international space station are constantly falling to earth, if not for the 14,700 mph speeds around earth to maintain orbit, earth’s gravity would pull astronauts directly towards the centre of earth by the combined strength of gravity...
Mate... I dunno where you're getting this stuff from, but whatever
its source, it's repeatedly erroneous.
Nothing is "falling towards the sun". Not human beings, nor our planet.
Centripetal and centrifugal forces are the forces experienced by rotating
objects such as the Earth. The centripetal force keeps an object moving
in a circle and is always directed toward the center of that circle.
For instance,
the gravitational force of the sun is a centripetal
force that keeps the Earth orbiting around it.
And astronauts in space are not "constantly falling to earth". The velocity
(not "speed") of the capsule has nothing to do with any gravitational effects
on the astronauts—in fact the mass of the Earth has no practicable effect on
the tiny mass of the human body at those distances separating them.
It's been estimated—for example—that the gravitational pull from a mosquito
on a human body is around the same as the gravitational pull of the moon on
that same body. But nowhere of course as great as the gravitational pull of
the Earth we stand upon.
