misapprehension About gravity in space.

Photo astronauts float Sleeping or exercising in space. Causing the belief that there is no gravity in space. The word "gravity-free" (zero gravity) were used in the study. Even among physicists and NASA's astronaut training center for astronauts called John. Glenn that their "Wireless Research Center of Gravity" (zero gravity Research Facility).

But the truth Gravity is the attraction toward each object that is available everywhere. Sun sent gravity planet. Moon attracts the world Even Apple's gravity attracts light in the environment. If the pilot study Blackhawks walked away from a large mass such as the Earth. Gravity is lower, but it never lost. But the astronauts floating about that. Because he was in a state of free fall continues into the world. Which made him weightless

Weightlessness astronauts

The spacecraft itself, it is under this description. Long space is still influenced by gravity, but by spacecraft far enough and fast enough to fly. It was pulled down to the ground and afloat. This condition is called Stawa. "The free fall" status to the International Space (iss) is moving at 27,700 km / h. This is enough to orbit the earth without falling. Simply put, the ISS status. It moves at a speed enough to move parallel to the curvature of the Earth. The crew of the International Space Station feel weightless. Because astronauts and space stations. Moving at the same speed It appears to be independent of gravity.

When on Earth Our bodies are drawn into. Earth with a force of 9.8 newtons per 1 kg mass called the first G in a state of free fall, you can not be pushed into the surface. The spacecraft no forces of space. So the astronauts do not feel the weight of their own.

Everyone has felt the microgravity seconds by hopping on a chair. But it also works the gravity of it.
