It is proposed that future space stations create an artificial gravity by rotating. Suppose a space station is constructed as a
800-m-diameter cylinder that rotates about its axis. The inside surface is the deck of the space station. What rotation period will provide "normal" gravity?
We must use the formula for centripetal acceleration:
We know the radius <em>r</em> and we want is to obtain a centripetal acceleration equal to <em>g. </em>Since velocity is distance over time, on this circle we can take distance as the circumference (which is of value ) and thus the time will be the period <em>T</em> because that's the time a point takes to travel the whole circumference, so we can write:
