   looking for the right term
  How would you call a stuff-that-applies-a-force?I'm planning a physics engine, and i imagine it like: plug in rigid bodies and let them interact under the influences of the forces (gravity, wind, drag etc). How would you call the base class from wich will inherit all the classes that applies forces on those bodies?I was thinking at "actuator", but it doesnt look very appropriate to me. Any idea?Thanks.   
  Impulse?   ;  Force?   ;  Effector, actuator?   ;Quote:Original post by jantaEffector, actuator?The correct term is in fact effector.;Quote:Original post by CyclesImpulse?No, the impulse is the change in momentum.I also think that a base class named "Force" makes sense.
