Distance To attain the maximum velocity, a certain minimum distance must be
traversed. This also applies to the braking phase.
If the traverse distance is greater than the distance covered during the
acceleration and braking phases, a movement at constant (maximum) speed
is inserted (see period of time from t
1
to t
2
in the figure below).
If the traverse distance is shorter, the maximum velocity is not attained.
