Acceleration is the time rate of change of velocity. If velocity is constant, then. acceleration is zero. Note: 100 km per h for 10 seconds is a constant speed, but not necessarily a constant. velocity, since we're told nothing about the direction.
Constant acceleration is notable for several reasons: 1  It is a fast form of travel. 2  Constant acceleration creates its own artificial gravity to the benefit of passengers, who may thus be spared from having to deal with the effects of microgravity.
