applyForce applyLinearImpulse waste time applying a zero force

[bobcgausa]

the other force functions do not exhibit this behavior
select examples 2 and 5 from the following iforces constant motion tutorial
https://editor.p5js.org/Bobcook47/sketches/dl63nTD8q

observe that velocity is continuously updated even when the object is stopped

and a mystery, at least to me
observe that when the box collides with the vertical wall on either side,
its angle transforms to 0.02 and never changes?

I wasn't able to see the problem in your example

note that the -0.00 values flicker
