The ideal solution, it’s been argued, is to design future spacecraft with the ability to impart some degree of artificial gravity on its passengers through centripetal force. The technique is ...

when the Earth orbits the sun it's because there's a centripetal force, gravity, that pulls them together. 'But in this case, it's the string doing the job of gravity.' DR YAN:There's enough ...

This centripetal force must be supplied by gravity which is also related to the radius of the orbit. So the trick is to find an orbital radius which works out to give a period of 24 hours. Can it be ...

This means that the closer the two objects are to each other, the stronger the force of gravity between them. If the force between them is greater, a greater acceleration will occur. The greater ...
