Relative Motion in Two Dimensions
... Relative Motion in Two Dimensions • The method for adding relative velocities also applies to motion in two dimensions. • As with one-dimensional motion, you first draw a vector diagram to describe the motion and then you solve the problem mathematically by resolving vectors into x and y components ...
