Sketchyphysics 3 friction
-
I would like to know how sketchy physic deal with frictional force ans if it possible to turn it off. Because I made a cycloid and I want to show with sketchy physic it tautochronous property. But because of friction, my ball that roll on it, stop to arrive at the bottom at the same time after their first ''cycle''. So it not a big problem for what I want to show but I would like to know if I can't switch off friction in order to see the tautochronous property until I restart the ''animation'' and not just after 1 cycle.
Thank.

Or in other words I only want to know why energy is not conserve in sketchyphysics. Because if they was no non-conservative force when a ball would be rolling it should never stop but it does.
