Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

A rocket is sent into space.  When the power dies out, the rocket will just keep floating and moving in space forever (unless an unbalanced force, such as a meteor, runs into it).
