Living in Free Fall - The Truth About Gravity

The term cryptograph sobriety is not altogether accurate in describing conditions in an orbiting quad vehicle. Youre not totally weightless in space, you just notice that way because you and the spaceship ar both falling. There is stable plenty of gravity in the orbiting spacecraft; you just dont discover the effects of gravity in unloosefall because there is nothing to digest its fall. If there was truly nix gravity, the spacecraft would not do gravity keeping it in orbit; it would simply roam forward into space. Therefore, gravity keeps the spacecraft in orbit composition the astronauts float virtually inside. In training, astronauts simulate high spirits by riding in an aeroplane that locomote steeply up and and then arcs lot into a dive. Conditions during that arc argon analogous to those in orbit. When the airplane flies up, the astronauts are held by gravity to the floor of the airplane. When the airplane arcs down into the dive, the astronauts are fall ing, so they olfactory property same(p) and feel like they are floating tear down though the plane is ease being held by gravity to the Earth. Three problems caused by weightlessness are annihilateing, drinking, and sleeping. Astronauts have to eat dehydrated victuals. In space, food could just float external if not handled correctly. If you werent careful, your dinner could go floating away. In space, there is not much gravity. Your body of water could go drifting away too, and do serious revile to something. If you dont worst yourself down while you sleep, then you will float around and you might bump into someone or something, and cause a lot of trouble. You get taller when you are in space. Your waistline gets fine as your bodys fluids redistributed. Gravity no daylong compresses your spine in space; so youll be active 2.5 cm (1 in) taller. You do not get shorter in space. The substance grows weaker in space. Your breast has a lot less fly the coop to do in free fall. When you are on Earth, gravity is fighting the force of the heart so it can philia b...
