306 Appendix 1 Introductory Physics Equation Sheet Equation Sheet for Physical Sciences Courses This equation sheet is intended for students writing tests or reviewing material. Therefore it is neither intended to be complete nor completely explicit. There are fewer symbols than variables, and so some symbols must be used for diFerent things: context must distinguish. The equations are mnemonic. Students are expected to understand how to interpret and use them. Usually, non-vector forms have been presented: i.e., forms suitable for one-dimensional calculations. 1 Geometry C cir = 2 πr A cir = πr 2 A sph = 4 πr 2 V sph = 4 3 πr 3 c 2 = a 2 + b 2 Pyth.Thm. 2 Kinematics d = vt v ave = d fnal d initial t v = at a ave = v fnal v initial t Amount = Constant Rate × time time = Amount Constant Rate a centripetal = v 2 r 3 Dynamics F net = ma 1 N 0 . 225 lb F centripetal = mv 2 r p =
