The force use the position, also the force compute some factor like the velocity, the gravity, etc…
So if you don’t want these thing you can directly use set the position.
Forces are of course slightly more cpu intensive but not that much. They are just a direction, and every frame the position is changed newCoordinateInThatDirection * TimeDelta() (if instant force then it moves by newCoordinateInThatDirection after substracting TimeDelta() from it).
This is out of memory I may be not 100% right but forces are really not that complicated and cpu intensive.
Tho forces from physics 2 are much more cpu intensive as there is a whole physics engine processing it
