Document Summary
Study of the fundamental laws of nature. The most widely used numerical system is decimal or base 10. The vigesimal or base 20 numerical system. The duodecimal base 12: egyptians divide the interval between sunrise and sunset into 12 parts using sundials (1500bc) Sexagesimal or base 60: the babylonians made astronomical calculations in the system inherited from. Each measurement is associated with a physical quantity. Distance from earth to the sun = (cid:883). 5 (cid:883)(cid:882)(cid:2869)(cid:2869)(cid:1865) Diameter of a period in a sentence = 5 (cid:883)(cid:882) (cid:2872)(cid:1865) An intrinsic unchanging property of an object. A measure of the gravitational force acting on an object, which can vary depending on the o(cid:271)je(cid:272)t"s lo(cid:272)atio(cid:374) Any valid formula in physics must be dimensionally consistent. Each term in the equation must have the same dimensions. M k h da d c m n p f. Multiplication or division: the number of significance is equal to the number of significant figure in the least accurately known quantity.
