Currently forces are additive in the Physics engine. It would be nice to have an option to make it not so. Instead of making the body static and then applying the new force.
Forces are additive in Box2D because they are additive in reality :)
However, if you're going for more of an "arcade" effect, you should be able to simulate non-additive motion by zeroing out the current motion before applying your next force:

For example, "SimplePool" does this to stop the cueball whenever the player is trying to shoot it again.
