Motion in Two and Three Dimensions

3.1 The Important Stuff

3.1.1 Position

In three dimensions, the location of a particle is specified by its location vector, r:

r = xi + yj + zk (3.1)

If during a time interval ∆t the position vector of the particle changes from r1 to r2, the

displacement ∆r for that time interval is

∆r = r1 − r2 (3.2)

= (x2 − x1)i + (y2 − y1)j + (z2 − z1)k (3.3)
