Formula for calculating distance required for rigidbody to come to a full stop

[ADaurio]

Did some more testing and this formula isn’t completely accurate. I’ve been looking into more drag calculations, but they all assume drag caps at 1, which is definitely not true in Unity.

Drag factor, what is it?

What does the rigidbody.drag value represent? Is is the Reynolds number or something arbitrary in PhysX? I can’t find any info on it, besides “it’s drag”. What I’m mostly seeking is information on the formula by which it affects the velocity of the rigidbody. I’m truly curious. Regards Klum

Physics drag formula?

Hi there, i have this situation where i need to apply different forces to an object and then apply the gravity manually, but this gravity can’t factor in the drag nor the mass of the object, meaning i want it to fall down as if the drag was 0 while not being set to 0 in the drag properties right now i have this rigidbody.AddForce(new Vector3 (0, -gravity * rigidbody.mass, 0)); this is enough to ignore the mass, but now i need to do some calculation to account for the drag of the object i kno…

The general consensus is velocity = velocity * ( 1 - deltaTime * drag); represents a FixedUpdate drag calculation, but that just gets weird when drag > 1.

Any more ideas or more accurate calculations?
