Description
sun 88 How has the distance between sun and earth been calculated? Also what is the size of the sun?.
sunwin-org-vn In fact both the Sun and the Earth are accelerating towards their mutual centre of mass so there aren't inwards and outwards forces - both forces are inwards towards the centre of mass. Anyhow, we call the (apparently) outward force on the Sun the centrifugal force from the Latin for fleeing the centre.
ảnh-rút-tiền-sunwin I quite liked this one [archived] describing measurements on cars. It shows that things left in the sun can get significantly hotter than the surrounding air (although there are some issues with the method used, the conclusions are mostly valid), One final note - how hot things are is not the same as how hot they seem to be.
