Gravitational Field

IB Physics: Gravitational Field

The myth is that Newton realised that an apple fell because of gravity but I don"t think he was the first person to notice that an apple fell because it was pulled downwards. The big breakthrough was to realise that the force pulling the apple down was the same force that held the Earth in orbit around the sun (at least this is the myth that I spread).For SL you don"t have to go into much detail about Gravitational fields...
