Aw: Gravity


Hi,

the physics simulation feature in Cinderella is not meant to be used for "real world". We are working with a simplified model, because if you start using the real constant of gravity, you also have to start working with real measurements on screen…

If you really want to do that, there is still a way: You can query the force that is applied to an element A of the construction using CindyScript:
A.f


If you just put a single mass (with 1 unit of mass) in the construction then you can adjust the gravity slider and/or the gravity arrow until the force matches the gravitational force with g=9.81 m/s^2. To do this, just place a single mass A in the construction, open the script editor (CMD-9) and put
print(A.f)
in the draw event. Then adjust until you like the force applied...

Does that work for you?

Ulli
