... • The place where a planet is furthest from the sun is called the “aphelion”. • In Newton’s theory this remains the same, orbit after orbit. • It was observed that the aphelion and perihelion of the planet Mercury advance by 43” (43 seconds of arc) per century, and so rotate completely around the su ...

Gravitational potential energy
... Of the four fundamental forces; the strong nuclear force, the weak nuclear force, the electromagnetic force, gravity has the most influence on our everyday life. It is responsible for the formation of stars, planets and galaxies. It keeps us from floating into space. Yet, gravity is the weakest of t ...
