Kinetic/Potential

So one major source of inspiration for games seems to be changing around different types of physics – people adjust gravity, space, time, but has there been a game that has exploited Newton’s third law of motion: that forces have an equal and opposite reaction. This could be made into a very interesting design principle, obviously objects that didn’t have any reaction would be boring (and further already exist as unaffected areas. What would be interesting is some kind of mechanism where the player could postpone the reaction – either giving or absorbing energy for a certain period. This could be used to, say, push a block over for a while and then have it accelerate over thin air. Or, absorb a certain amount of damage/impact in order to generate more powerful moves. Further, this seems like it would be a pretty simple physics system to create.
