Unformatted text preview: 122 Chapt. 14 Gravity 014 qmult 00150 1 4 5 easy deducto-memory: gravitational constant 6. Lets play Jeopardy ! For $100, the answer is: It is the gravitational constant with MKS units Nm 2 / kg 2 It is actually the poorest known of the fundamental constants because gravity is such a weak force between laboratory size objects which are used to measure it. What is , Alex? a) 1 . 000 ... b) 2 . 99792458 10 8 c) 2 . 99792458 10 8 d) 6 . 67428(67) 10 11 e) 6 . 67428(67) 10 11 014 qmult 00160 1 1 4 easy memory: point-like gravity law 7. Newtons classical gravity law is written for point masses. But this presents a paradox since point masses, at least classical point masses (and maybe not even quantum mechanical point masses, but who knows) do not really exist. The paradox is resolved by regarding the law as an ideal limiting form from which actual gravitational forces between masses can be calculated....
