The red DOT line in the chart shows that the centripetal forces of the planets at their respective positions do not correspond to the gravitational law Gravitational force = Centripetal force. The ...

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 ...

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 ...

Since the gravitational force Fgr is always acts along line OP ... acceleration in terms of its tangential and normal components (rate of change of speed and centripetal components) being shown in ...
