Additional visibility options for 'More Data' #187

Open oliver-phet opened 3 years ago

oliver-phet commented 3 years ago

Currently, I always see mass and have the option to also see velocity & momentum

It would be nice if I could add velocity and momentum information independently. This would enable teachers to stage calculations for their students.

The position data: is not very useful to me and there is no option to hide it. It serves only to distract my weaker students from the important information

This is an interesting request, and I can see why a teacher may not want to display the value of velocity and momentum simultaneously. Given how close this sim is to the finish line (and the fast-approaching Flash sundown), I don't think this is something we should consider for initial publication.

One way we could do this would be to have checkboxes for position, velocity, and momentum. Checking any one checkbox would switch the Mass controls to a display instead of a slider. image image image

This muddies the design, but adds flexibility. I'm curious to know if this would be a common request, so let's leave this open but deferred. If we don't receive more requests within a year of publication, we can close.
