Inheritance diagram for StepCore::WeightForce:
Detailed Description
Weight force (constant gravitational force).The force acts between on massive bodies (currently only Particle) and equals:
![\[ \overrightarrow{f} = \left( \begin{array}{c} 0 \\ mg \end{array} \right) \]](form_13.png)
where:
is Particle::mass
is WeightForce::weightConst
- Todo:
- Add interface for massive bodies, support bodies with distributed mass
