2.4 Equations of Kinematics for Constant Acceleration It is customary to dispense with the use of boldface symbols overdrawn with arrows for the displacement, velocity, and acceleration vectors. We will, however, continue to convey the directions with a plus or minus sign. o o t t ! ! = v v a r r r o o t t ! ! = x x v r r r o o t t x x v ! ! = o o t t v v a ! ! = _ _
2.4 Equations of Kinematics for Constant Acceleration o o t t x x v ! ! = 0 = o x 0 = o t ( ) t v v t v x o + = = 2 1 Let the object be at the origin when the clock starts. t x v = True for constant acceleration
