Hi , people
Life in a space ship
1 -
2-
If gravity does exist in space why is this true??
3-
also why??
4-
because when the acceleration increases the force acting upon the astronaut increases ??right??
5- If gravity does exist in space so why objects float in space??
6-
so what is the idea of propeller jet chair if its an application to Newton's third law??
Thanks
Life in a space ship
[/QUOTE][quote name = "My book"]
It must be a unique experience to live without weight in a space ship...everything is normal in a spaceship such as oxygen,pressure but there’s no gravity so :
* You can’t drink without using a straw because
liquids don't go down .
* You can lift a big man with one finger.
* You can jump up high and stay hanging.
* Plant roots grow upwards due to the absence
of gravity.
* According to Newton’s third law,if you throw
a mass to front ,it pushes you back
with the same force.
*during launching rockets astronauts are under sever or deal(according to Newton's second law)

How come?what does the book mean?gravity does exist in space! I'm really confused!It must be a unique experience to live without weight in a space ship...everything is normal in a spaceship such as oxygen,pressure but there’s no gravity so :

Life outside the spaceship:
Astronaut must use the propeller jet chair(which is an application to Newton's third law) to move anywhere in the space looking like a satellite.
so what is the idea of propeller jet chair if its an application to Newton's third law??
Thanks
