The Ramp

 

Friction vs. No Friction.

Labels near tips of arrows.

 

Bugs:

Thermal Energy computation has errors near v=0 regions.

Arrows should be offset (non-overlapping).

Screen turds with zero-potential graphic.

Force Arrow text appears at (0,0) sometimes.

Arrow text label centering fails for arrows at angles.

 

Refactor:

How is the transform being handled?

Factor out arrow names.

Ramp length should be parameter.

 

Questions:

Graph friction/normal/gravity force as a function of angle?

Open boundaries?  (Launch off the up-side, slide onto horizontal on the down-side?)

What should the ‘jack’ look like?  (The thing that props up the ramp.)  Stack of books?
