Imagine some kind of mechanical satellite drifting through space, and there are several dozen thrusters around its perimeter-sphere. Each one, individually, moves in a unique direction, quality, and exerts a certain force, quantity. And yet, these thrusters can be harmoniously programmed to steer the satellite - by having many adjacent thrusters activate simultaneously, their averaged direction is where the satellite moves. By activating a thruster that is aimed against that average direction, we can program for resistance of deceleration.
