I had a read, but it didn't get me very far, sorry – competing with an Alan Kay presentation is always going to be tough :-) Regarding Physics, it's more a sandbox for making weird and wonderful little mechanical devices; but specifically regarding gravity, I think there is a nice feature I'd like to try and find a way add as some point, 'object trails'. With this you could roll a ball off a cliff edge and see the motion curve left behind. Would be quite easy to add a grid overlay to allow measurement. I guess an optional gird would also allow building other more accurate experiments (i.e. I just made 3 pendulums of different lengths to see the shortest pendulum swing faster; and that using a larger mass weight did not affect frequency). --Gary > On Mon, Jun 8, 2009 at 11:39 AM, Brian Jordan<[email protected]> > wrote: >> Attaching Sugar Devel (people who want to be involved with Physics >> development might be on there). >> >> >> On Mon, Jun 8, 2009 at 5:28 AM, Asaf Paris >> Mandoki<[email protected]> wrote: >>> Hi, >>> >>> I've managed to get my development environment working and started >>> hacking >>> the Physics activity.
