Inheritance diagram for StepCore::CoulombForce:
Detailed Description
Coulomb electrostatic force.The force acts between pairs of charged bodies (currently only ChargedParticle) and equals:
![\[ \overrightarrow{f} = k_C \frac{q_1 q_2 \overrightarrow{r}} {|\overrightarrow{r}|^3} \]](form_0.png)
where:
is CoulombForce::coulombConst
and 
is ChargedParticle::charge of the first and second body
is difference of Particle::position of the first and second body
- Todo:
- Add interface for charged bodies, support bodies with distributed charge
