Detailed Description

Weight force (constant gravitational force).

The force acts between on massive bodies (currently only Particle) and equals:

\[ \overrightarrow{f} = \left( \begin{array}{c} 0 \\ mg \end{array} \right) \]

where:
$m$ is Particle::mass
$g$ is WeightForce::weightConst

Todo:
Add interface for massive bodies, support bodies with distributed mass

Reimplemented from StepCore::Item.

Definition at line 165 of file gravitation.h.

void StepCore::WeightForce::setWeightConst ( double  weightConst  )  [inline]

Set weight constant.

Definition at line 158 of file gravitation.h.

double StepCore::WeightForce::weightConst (  )  const [inline]

Get weight constant.

Definition at line 156 of file gravitation.h.

WeightForceErrors* StepCore::WeightForce::weightForceErrors (  )  [inline]

Get (and possibly create) WeightForceErrors object.

Definition at line 161 of file gravitation.h.
