Figure 2: Velocity and acceleration for nonuniform circular motion: the velocity vector is tangential to the orbit, but the acceleration vector is not radially inward because of its tangential component a that increases the rate of rotation: d/dt = a/R. ^ A. are called, respectively, the radial and tangential components of acceleration. For the case of constant acceleration, the differential equation Eq 1) can be integrated as the acceleration vector A of a point P is constant in magnitude and direction. Furthermore, the velocity is tangent to the trajectory of the particle at every position the particle occupies along its path. See also.
