SAT Subject Physics Formula ReferenceThis guide is a compilation of about fifty of the most important physics formulas to knowfor the SAT Subject test in physics. (Note that formulas arenotgiven on the test.) Eachformula row contains a description of the variables or constants that make up the formula,along with a brief explanation of the x tvave= average velocity x= displacement t= elapsed timeThe definition of average (vi+vf)2vave= average velocityvi= initial velocityvf= final velocityAnother definition of the av-erage velocity, which workswhenais v ta= acceleration v= change in velocity t= elapsed timeThe definition of acceleration. x=vi t+12a( t)2 x= displacementvi= initial velocity t= elapsed timea= accelerationUse this formula when youdon t havevf.
SAT Subject Physics FormulaReference Kinematics(continued) v2 f = v 2 i + 2a∆x v f = final velocity v i = initial velocity a = acceleration ∆x = displacement Use this formula when you don’t have ∆t.
