With what speed must a space station of 60m radius rotate to produce at its outer rim an artificial gravity equal to true gravity(as on the surface of earth)? keep in mind that the space station produce the gravity of 9.8m/sec.sec..

1 Answer 1


The acceleration equation is : enter image description here with gamma : acceleration (m.s^-2), v : speed (m.s^-1), r : radius (m), omega : rotational speed (s^-1)

Here you want gamma = 1g = 9.8 m.s^-1 and r = 60m

So enter image description here. Which results in w (omega) = 0.4041 rad.s^-1 = 3.86 tr/min
