What is artificial gravity?

Weightlessness in space crafts or satellites is highly is highly convenient to an astronaut in many ways.For Example he can not drink in it.It is very difficult for him to perform experiments.

In order to overcome these difficulties an artificial gravity is created in the space craft by spinning it around its own axis so that normal force of gravity can be supplied to the occupants in the space craft.

To find the spinning frequency ,space craft consisting of two chambers connected by a tunnel of length “2R” .If “ν”

be the frequency of the tunnel and “T” be its time period then.

ν = 1/T

The magnitude of the centripetal acceleration “ac” which is equal to the magnitude of the centrifugal acceleration given by:

artificial gravity equation

To create artificial gravity equal to the gravity at the surface of the earth,put ac = g in equation (1)

artificial gravity  at earth surface

Thus the astronaut should feel comfortable in space craft if it is spinning at 9.5 revolution /minute at a distance of 10 m away from the axis of rotation.
