2010 t x v = [average speed = (distance)/(time)] Velocity is a vector! Speed is the magnitude of the velocity vector. ( 29 t x x t x v o - = = [instantaneous velocity = (change in distance)/(change in time)] t v a = [average acceleration = (change in velocity)/(time)] Acceleration is a vector! t v a = [instantaneous acceleration = (change in velocity)/(change in time)] When given a graph of distance versus time, the slope is the velocity. When given a graph of velocity versus time, the slope is the acceleration. Workhorse Equations (for constant acceleration) t ) v v ( a o - = ( 29 o 2 o 2 x x 2 v v a - - = t 2 v v x x o o + + = 2 o o at t v x x 2 1 + + = 2 2 s ft 32 s m 8 . 9 g = = θ = cos v v x 0 C Bx Ax 2 = + + A 2 AC 4 B B x 2 - ± - = θ = sin v v y a m F = [Force = (mass)(acceleration)] 2 y 2 x v v v + = Force is a vector! unit is N = Newton x y v v tan = θ Frictional Force is opposite to direction of motion. In equilibrium, the sum of all forces acting on a body is zero.
