We can define the displacement vector, →d, as the vector from position →r1 to position →r2: \[\begin{aligned} \vec d = \vec r_2 - \vec r_1 =\begin{pmatrix} x_2-x_1 \\ y_2-y_1...We can define the displacement vector, →d, as the vector from position →r1 to position →r2: →d=→r2−→r1=(x2−x1y2−y1z2−z1)=(ΔxΔyΔz) The displacement vector is such that one can add the vector →d to the vector →r1 to describe the new position of the object at time t2: \[\begin{aligned} \vec d &= \…
