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.

const friction = Forces.velocityForce(0.00001, `multiply`);

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.

const drag = Forces.magnitudeForce(0.1, `dampen`)
