Skylab 4 commander Jerry Carr joking with his crewmate Bill Pogue. Carr is demonstration how easy it is to balance a crewmate on one's fingertip in weightlessness.

Just imagine a clothes dryer, how it spins, up and away from gravity, and also down and towards gravity. The turning device is in the center of the object being turned. With 'Centripetal Force for Circular Motion', if it is fast enough at a constant speed, the object inside a container being spun will stay in the one spot against the side of the container or a dummy fake space station. However because of the 'Centripetal Force Principal', the object inside the container has a tendency to move towards the center of the container, thereby creating its own center of gravity within the container.
Remember the object would stay in the one spot against the side of the spinning container, unless another external force pushes the object towards the center, an inanimate object cannot push itself away from the side of the spinning container, however a human has its own external/internal force, to push themselves, and other objects, as is shown in the fast spinning dummy International space station.
Astronauts use the force of their legs or arms to push themselves & objects to the center or away from the sides of the dummy space station, and the astronauts and objects move, or float within the center of the spinning container.

You may wish to check out the vast evidence provided in this forum for more answers to your questions.
1. What physical law explains/demonstrates the impossibility for an astronaut to jog/run in a man-made space module, as the above video purports to show? The author of the video claims this is demonstrable proof of the unfeasibility of human space travel as shown in the SkyLab footage.
