Friction & Drag
Friction reduces speed with the velocityForce . This force essentially scales the current speed by the force value. By passing multiply
as the second parameter, we can enhance the force with mass - heavier object, more friction.
Drag also reduces speed, and is based on the the square of the current velocity. We can use magnitudeForce . This produces a non-linear relation, compared with velocityForce
. By passing dampen
as the second parameter, we could reduce the force according the greater the mass - heavier object, less drag. Whether that makes any sense depends ont the dynamics you are creating.
