... 2. What do you call the sum of all of the forces acting on an object? The net force. 3. Describe the difference between a balanced and unbalance force. Balanced forces are equal but in opposite directions so there is no motion as a result, while unbalanced forces are unequal which cause an object to ...

This system rescales the magnetic field (thus the derived quantity electric field implicitly) in such a way that factors of 4π and the speed of light c are absorbed into the physical variables. As a result, they simply can be substituted by unity. Of course, this does ...
