1.1 - 1D Kinematics

ˉv

x/t

scalar

quantities described by a magnitude (numerical value)

vector

quantities described by both magnitude & direction

distance

scalar quantity referring to how much ground an object has covered during motion

displacement

vector quantity referring to object’s overall change in position

avg velocity

displacement / time

position/time equation

x = v_ot + ½ at²

velocity/time equation

v = v_o + at

constant velocity

x=vt (+v_o)

kinematics equation “w/o time”

v²= v_o²+ 2ax
