Vector kinematics with applications THEORY There are six kinematic terms. These definitions (really all definitions) should be memorized . time , t … reading of a stopwatch time interval , t t f - t i … difference in two times position , r … vector from an origin to the location of a particle r (t) = x(t) i + y(t) j graph of r displacement , r r f - r i … difference in two positions graph of r velocity , v r / t … this is average velocity over t, in the limit t 0, this becomes v d r /dt = dx/dt i + dy/dt j = v x i + v y j v points parallel to the tangent to the path of motion acceleration , a v / t … this is average acceleration over t, in the limit t 0, this becomes a d v /dt = d 2 r /dt 2 = d 2 x/dt 2 i + d 2 y/dt 2 j = dv x /dt i + dv y /dt j
