The
law of universal gravitation
|
The accelerated fall of bodies to earth led Newton to assume that our planet attracted all the bodies that surround it towards its centre. Kepler's laws of planetary motion convinced Newton that the sun in turn attracted all the planets towards itself. Newton's genius lies in his ability to reach a general rule: the law of universal gravitation. |
