Astronauts floating around inside the space shuttle are not actually in a zero-gravity environment. explain what is the real reason astronauts seem weightless.

For the answer to the question above, imagine they are traveling at approximately 17,500mph, at a tangent to the Earth, so, in absence of gravity, would be propelled away from the Earth like a slingshot. But the Earth's gravity pulls them in at the same rate, so that the net effect is zero, and they circle the Earth instead of flying off at the tangent.

Answer (true);
