What happens to your bones when you are weightless, is that your bones will get weaker and weaker. That is why everyday, astronauts, have to spend two hours on a treadmill everyday of there space expedition.
The statement that astronauts on the Moon are weightless is true.
when the rockets stop firing, astronauts begin free fall (weightless).
i like turtles
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.
Because of gravity
What happens to the bones when muscle shortening
Hollow bones, curved wings to make them aerodynamic and light feathers to make them almost weightless.
bones get rusty
No. It is light -- not heavy, but it is not weightless.
A shadow is something that is weightless but can be seen.
buned bones become brittle
When you jump you would stay in the air for a long time before coming down. So basically your weightless...
Something is weightless when there are no gravitational forces acting upon it.
"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).
When a babtilage is slowly replaced by bones.
The whales bones got dissolved in the sea..
what happens to the monkeys when they die in the rainforest
