| The net forces acting on each column are summed to derive the net force and torque acting on the assemblage of columns. |
| As the electrons are free to move they do so until they find positions where they feel no net force. |
| Conversely, if a body is not accelerated, there is no net force acting on it. |
| The result is to generate a net force that tends to straighten out the curve into a cylindrical tube. |
| The farther away a quark moves, the more gluons appear, each contributing to the net force. |
| For a body to be in equilibrium, there must be no net force acting on it. |
