I am a school teacher and as I explain various functions to my students I need to understand them fully so that I'm able to teach them properly. I've come across phent_setdamping and I'm a bit confused. I understand it's used for airdrag/friction but don't quite understand the following;
1) is linear damping the force (air) directly opposing the movement of the entity? That is, if a ball is moving to the right the air is opposing the ball's movement and that opposition (air drag) is linear damping?
2) if that's the case with linear damping, what's up with angular damping? I'm not quite sure what the need is for angular damping... isn't it essential the same as linear damping except from another angle, what I mean is, if the ball is rolling to the right linear damping is opposing the ball's movement (air drag) so what exactly is angular damping doing?
