"Weight" happens when the attraction of gravity on a mass is resisted, we only FEEL the weight when we are resisting gravity. Weightlessness therefore happens when gravity is not resisted - when you are in "free-fall".
In a space when you are in orbit round the Earth, you are effectively in "free-fall" and therefore as you are not resisting gravity you are weightless (but not massless).
yes
Technically, as an astronaut is weightless in space, so should a space shuttle!
weightless is just a figure of speech. things in space are just lighter than they are on earth. the space shuttle weighs 220,000pds so in space it might weigh 100,000pds.
A space shuttle feels like a smooth ride during liftoff with a sense of acceleration and increased G-forces. Once in space, the shuttle feels weightless and the sensation is often described as floating. Reentry can feel turbulent and intense as the shuttle reenters the Earth's atmosphere.
They actually are weightless, due to the fact there is no gravity in space. However a sky-diver would say he/she feels weightless, but they are experiencing free-fall.
Yes
yes there are
Because of gravity
astronaut
The driver of a space shuttle is called an astronaut.
An astronaut
To bring any astronaut into space! I hope you like my answer!
