Living in Free Fall - The Truth About Gravity

The term zero sombreness is non completely surgical in describing conditions in an electron orbiting space vehicle. Youre non totally weightless in space, you scarcely feel that commission because you and the spaceship atomic number 18 both falling. There is still the great unwashed of gravity in the orbiting space vehicle; you just wear offt feel the effectuate of gravity in freefall because in that respect is nothing to resist its fall. If in that location was truly zero gravity, the spacecraft would not have gravity keeping it in orbit; it would simply roll extraneous into space. Therefore, gravity keeps the spacecraft in orbit while the astronauts float around inside. In training, astronauts assume weightlessness by horseback riding in an airplane that locomote steeply upward and hence prows trim back into a dive. Conditions during that arc ar similar to those in orbit. When the airplane flies up, the astronauts ar held by gravity to the scandalise of th e airplane. When the airplane arcs down into the dive, the astronauts atomic number 18 falling, so they look exchangeable and feel like they are locomote even though the plane is still existence held by gravity to the Earth. ternion problems caused by weightlessness are eating, drinking, and sleeping. Astronauts have to eat dehydrate food. In space, food could just float away if not handled correctly. If you werent careful, your dinner could go floating away. In space, there is not much gravity. Your water could go drifting away too, and do serious damage to something. If you dont strap yourself down while you sleep, then you pull up stakes float around and you great power bump into someone or something, and cause a pickle of trouble. You shoot for taller when you are in space. Your waistline gets thinner as your bodys fluids redistributed. gloominess no longer compresses your spurring in space; so youll be about 2.5 cm (1 in) taller. You do not get shorter in space. Th e heart grows weaker in space. Your heart has a treat less work to do in free fall. When you are on Earth, gravity is armed combat the force of the heart so it can pump b...
