How do I make glider physics?

whether it be with the physics function, or just with code, I was wondering if there would be any way for me to create physics for a glider. like in learn to fly. http://armorgames.com/play/3789/learn-to-fly. I was wondering because I wanted to make a game involving a paper airplane, and this would apply.

If you can break down "glider-physics" into what you want to happen under what circumstances, you can create the conditions and the actions..

If think you can achieve that just by playing with the game gravity, acceleration, fall speed and stuff like that

Okay, thanks

Drag and lift are the two things that would make it different than a flying projectile like a rock.

Drag slows the plane down. It slows down slowly if the plane is pointed in the direction of motion. If the plane is perpendicular to the direction of motion then it will slow down fast.

Lift is caused when the plane is moving fast and is pointed in the direction of motion. It causes a force perpendicular to the plane.

You can google the formulas for these or you can fake but know the more accurate you make it the better it will probably look.

I played through that penguin game. it seems to be using a decent aerodynamic lift model. If you are interested in doing some maths, I like https://www.grc.nasa.gov/www/k-12/WindT ... rmula.html

Okay, Thanks again guys
