In free fall do all objects fall with the same acceleration? yes, objects fall at a rate of 9.8m/swith acceleration. For every second in free fall you must add 9.8m/s to get the acceleration of an object.
The Space Station hasn't escaped Earth's gravity at all; it's experiencing about 90% the pull that we feel on the surface. To avoid falling back into the atmosphere, you have to go sideways really, really fast. The speed you need to stay in orbit is about 8 kilometers per second.[4]It's a little less if you're in the higher region of low Earth orbit. Only a fraction of a rocket's energy is used to lift up out of the atmosphere; the vast majority of it is used to gain orbital (sideways) speed.ow fast is 8 km/s, anyway? I think the reason for a lot of confusion about these issues is that when astronauts are in orbit, it doesn't seem like they're moving that fast; they look like they're drifting slowly over a blue marble. But 8 km/s is blisteringly fast.
