What is the mechanism (in simple words) of artificial gravity?pls dont copy paste from the sites on the internet becoz i have already browsed a lot....

Artificial gravity can be created using a centripetal force. A centripetal force directed towards the center of the turn is required for any object to move in a circular path. In the context of a rotating space station it is the normal force provided by the spacecraft's hull that acts as centripetal force.
