SAT Subject Physics Formula Reference This guide is a compilation of about fifty of the most important physics formulas to know for the SAT Subject test in physics. (Note that formulas are not given on the test.) Each formula row contains a description of the variables or constants that make up the formula, along with a brief explanation of the formula. Kinematics vave = average velocity x The definition of average ve- vave = x = displacement t locity. t = elapsed time vave = average velocity Another definition of the av- (vi + vf ). vave = vi = initial velocity erage velocity, which works 2. vf = final velocity when a is constant. a = acceleration v a= v = change in velocity The definition of acceleration. t t = elapsed time x = displacement 1 vi = initial velocity Use this formula when you x = vi t + a( t)2 don't have vf . 2 t = elapsed time a = acceleration x = displacement vf = final velocity 1 Use this formula when you x = vf t a( t)2 t = elapsed time don't have vi.
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.
