The velocities along the X and Y axes are such that the direction of motion follows the specified path, yet the vector
velocity fits the vector speed and acceleration requirements.
velocity fits the vector speed and acceleration requirements.
For example, the velocities along the X and Y axes for the path shown in Fig. A.13 are given in Fig. A.15.
Fig. A.15a shows the vector velocity. It also indicates the position point along the path starting at A and ending at
D. Between the points A and B, the motion is along the Y axis. Therefore,
D. Between the points A and B, the motion is along the Y axis. Therefore,
Vy = Vs
and
Vx = 0
Between the points B and C, the velocities vary gradually and finally, between the points C and D, the motion is in
the X direction.
