### Paradigm Shift: Motion by means of Induced Internal Forces

Fig.1 -

**Proof of concept**. Action--reaction forces in isolated systems. Upper:**Induced internal forces**. Redeployment of the center of mass and acceleration of the system. Lower:**Collinear internal forces**. No change in the center of mass and no acceleration of the system.**Attention!**The induced internal reaction force was not deliberately inverted (same direction with the induced internal action force) but as a consequence of the mathematical proof.
