Physics 211 Fall 2001 Concepts and Equations t v a = Defines acceleration in terms of how the velocity changes. v v v i f + = How two instantaneous velocities are related to the change in velocity. t x v ave = Or the “mid-time” velocity. Defines displacement and average velocity. a x t = 2 Only if the initial velocity is zero. May not use this to find x or acceleration. hyp opp = θ sin hyp adj = cos adj opp = tan g m W A A E = , B A k B A N f , , μ = Kinetic friction B A s B A N f , max , = Max static friction a m F net = Second Law
