Bar graphs are 2D
Bar graphs & charts are colorized consistently.
Added Wall barriers.
Added timer graphic.
Added Speedometer. (speed readout)
Added Piano.
Deleted sleepy dog.
Book stack can be dragged to set ramp height.
Added wheels for no friction case.
Rescaled force arrows & bar graphs to fit better.
Flat ground no longer wooden.
Renamed frictive to friction force.
Curly brace label for bar graphs.
Background added for bar graphs.
Ramp world & readouts scale independently now.
Bugfixes:
blue arrow on flat area has been
removed.
misc. bugfixes
sky & earth fit better.

Add option to graph
Parallel Components of forces
- Better organization of
screen real estate
- Bar Graphs
- Move to Right side (or
Top Left of screen?)
- Avoid confusion
regarding graphing force or work due to force.
- Better labels for the
graphs.
- Show all grab bag
choices at once? (if we have room, maybe on intro panel.)
- Don’t show bar graphs
and charts simultaneously. (at least optional to not).
- Set object at top of
ramp and have it stay while you get ready to release.
- A hook?
- Set infinite friction?
- When ramp overheats,
show a “Warning, Ramp overheated” and a reset button.
- Maybe hide coordinate
views in an advanced (expandable) panel.
- Checkbox to show energy
bar graphs and/or work bar graphs, selecting them will help the user
know what they’re looking at.

force.

resolution.
- Audio (for crashes)
- Performance Enhancement.
- Improve screen layout.

Bugs:
Arrows (and labels)
should be offset
(non-overlapping).
Especially
problematic for small force arrows.
Arrow text label
centering fails for arrows at
angles.
Debug energy
conservation.
Energy
is lost at ramp-surface conversion.
100% processor while
just sitting (graphs
visible)
Zoom on charts doesn’t
work.
Force arrows should
show on init.
Questions:
- Add plots of PE vs time
and KE vs time.
- Are these supposed to
be separate plots, or on the same plot?
- Different
coordinate-frame vectors should have different patterns?
- Bar Graphs should have
Labels on the bottom (see springs & masses)?
- This is problematic for
bar graphs that go negative. I’ll leave
it, unless one thinks otherwise.
- It has been suggested
to rename or
coname Applied Force to Push or Man or Applied (push) or something like
that. I don’t think students will easily
make the connection between applied and the push.
- "I’d like to see
something connecting the work done to the growth of the energy graph. It’s not there right now."
-What's this about?
