Physics - No loss of energy?

I set my object in motion using physics.applyForce at time of creation.

The objects collide with the walls I have set up, but, as is expected, there is a loss of energy when they collide (they start moving slower).

I don’t want them to lose energy (speed) I want them to always be moving at the same speed, yet still bounce around.

Any pointers into values to tweek?
