1. yes your weight becomes zero. Weight = mass x gravitational acceleration, which is also zero.
2. maybe- your body mass can go up or down in space, depending on how much you eat and exercise, just like on Earth.
Yes your weight does change in space β it becomes zero!
However, your mass does not. Astronauts can actually figure out how much mass they are in space by using a special rocking platform that swings them back and forth.
It is a little bit more complicated than on Earth but they canβt just stand on some bathroom scales as it wonβt work!
