i like turtles
yes there are
Because of gravity
They are in the vacuum of space.
the absence of the gravitational force or field in space causes the astronauts to become weightless
They do not. Astronauts in space are effectively weightless, so for them, there is no up or down; the idea of "upright" has no meaning.
Yes, but they do have the same mass. Weight is based off the effect of gravity pulling something down, because there is no gravity in space astronauts are weightless.
No, astronauts do not lose their memory when they are weightless in space. However, some astronauts may experience temporary cognitive changes due to factors such as radiation exposure, sleep deprivation, or stress, which could affect their memory.
As there is no gravity in space, everything will float........... Because They're in free fall ........
Airplanes do not fly high enough to be unaffected by the force of gravity.
In microgravity of space, astronauts don't use their leg muscles as much, leading to muscle atrophy. This can result in skinny legs when they return to Earth. Regular exercise and physical therapy help astronauts regain muscle mass and strength.
Weight is an expression of the gravitational force acting on an object. When the space shuttle is in orbit around the Earth, it is held there by the Earth's gravity. Since gravity is still acting on the shuttle and the astronauts inside, they still have weight. They are described as "weightless" because an object in orbit is in a constant state of free fall.
