how and to add forces

[Dr_kola]

I want to do a simulation of a ball throw with air friction base on a program i written so I need that air friction will affect it but the air friction in algodoo isn't right so i want to now if i can add my own forces to act on the ball F=something that will effect the movement of the ball.
thanks for any help .
and sorry for my bad English.

What's wrong with algodoo air friction?
As alternatives you could use velocityDamping (in script window) and thrusters with scripted force.

Hello, Dr_kola
maybe the air friction is too little for your purpose?
You can right-click on the green ball right of the red apple, thats the place for modifying the air-friction.
e.g. you can set it to 50
There is also a linear term and a quadratic term which you can set or modify wit the sliders.
If any other questions to it, post here.
