Detailed Description

Weight force (constant gravitational force).

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

where:
is Particle::mass
is WeightForce::weightConst

Todo:

Add interface for massive bodies, support bodies with distributed mass

Constructor & Destructor Documentation

StepCore::WeightForce::WeightForce

(

double

weightConst = Constants::WeightAccel

)

Constructs WeightForce.

ObjectErrors* StepCore::WeightForce::createObjectErrors ( )

inlineprotectedvirtual

Creates specific ObjectErrors-derived class (to be reimplemented in derived classes)

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
