So this one equals m1 g cosine alpha - and this one, the x component-- which is in the minus x direction now-- equals m1 g sine alpha. 得到m1gcosα,而x方向上-,这里是x负方向-,大小是m1gsinα - 2
G The gravitational constant G - is an extremely low number-- - 6.67 times 10 to the minus 11-- in our... as our units, which is newtons, gram-meters per kilogram or something like that. 万有引力常数,是一个非常小的数字-,=6。67乘10的-11次方-,每公斤克米，或者类似的,它是个极端小的数字。 - 3
This holds for acceleration down Fs=m and so I get F of s equals m times g minus a.
