Answer to Question #160149 in Field Theory for Ariel

Question

How can you account for the sensation of 'weightlessness' experienced by the occupant of a space capsule
(a) in a circular orbit round the earth
(b) in outer space? Give one other instance in which an object would be 'weightless'.

Answer 1

Answer

a) according to physics concepts, Astronauts who are orbiting the Earth often experience sensations of weightlessness.

These sensations experienced by orbiting astronauts are the same sensations experienced by anyone who has been temporarily suspended above the seat on an amusement park ride.

Not only are the sensations the same (for astronauts and roller coaster riders), but the causes of those sensations of weightlessness are also the same.

b) in outer case that is the condition in which people or objects appear to be weightless. The effects of microgravity can be seen when astronauts and objects float in space. Microgravity can be experienced in other ways, as well. ... In microgravity, astronauts can float in their spacecraft - or outside, on a spacewalk.
