This distinction is interesting. I have several questions:
1. As primary forces are repulsive, then are secondary forces atractive?
2. Do you devide between two types of kinetic energy (one for each of the primary forces) and between two types of the potential energy (one for each of the secondary forces)?
3. Isn't mass a type of potential force? If so, how could gravity be a secondary force?
