Learning Goal: To be able to calculate position, velocity, and acceleration of an object in curvilinear motion using a rectangular coordinate system. An object's motion can be described along a path represented by a fixed x, y, z coordinate system. In such a system, the position vector, r, is described as r = xi+yj + zk The object's velocity, v, can be found by taking the first time derivative of the position vector, r: dr Vai + vyj + vzk dt The object's acceleration, a, can be found by taking the time derivative of the velocity, v: =d=azi+ayj+azk = a= dv dt =
