Is it possible for two objects to travel in opposite directions with out any work if they have opposing forces? I attached a diagram to show what I am trying to say. The boxes in the diagram are moving from position 1 to position 2.

Diagram doesn't help much.
Anytime there is force on a body that is moving, there is work.

This might be a better way to ask.

Is it possible for the two objects to use each others opposing forces to travel with out any work(other than friction)?

Opposite Direction/Opposing Forces


I still have basically no idea what you're talking about, except that it seems to be a free-energy something or other. I'm pretty sure the answer is no.

Work is a scalar, not a vector. Since the forces are opposing the direction of motion, they are both doing negative work. Both closed systems would be losing energy.
