Unformatted text preview: Ratios: the logical way (see slide) How do we find out the acceleration due to acceleration? o I.E. how fast do things fall towards the earth? F= G(M 1 M 2 /d^2) F=MA => A=F/M o M 2 =cabbage=M c o M 1 =Earth=M E o d=radius of earth=R E Ac=[GM E M C /R E ^2]/M C A C =GM E /R E ^2 A C =9.8meters/sec^2 DOES NOT DEPEND ON THE MASS OF THE CABBAGE A E =[GM E M C /d^2]/M E A E =GM c /d^2 A E =tiny Which falls faster – a cabbage or a potato? o They both hit at the same time...
