When settings the force or torque limits to [-FLT_MAX, FLT_MAX] a velocity motor will accelerate the bodies to the desired relative velocity in a single time step (if no other forces act on those bodies).

-Position motors have two additional parameters: Frequency (MotorSettings::mFrequency, Hz) and damping (MotorSettings::mDamping, no units). They are implemented as described in [Soft Contraints: Reinventing The Spring - Erin Catto - GDC 2011](https://box2d.org/files/ErinCatto_SoftConstraints_GDC2011.pdf).

You can see a position motor as a spring between the target position and the rigid body. The force applied to reach the target is linear with the distance between current position and target position. When there is no damping, the position motor will cause the rigid body to oscillate around its target.
