I was showing my AP physics class a variety of methods for solving 1-d
elastic collisions and I came across something fun that I had never seen
I hope it's true.
possibly related? :
What difference can be expected by the collision of a point mass and an
extended one. [elastic]
Two trials:
[1] the point mass's direction is coincident (collinear)with the
direction from the CoM to the contact point. And
[2] not, so a rotation is imparted.
bc viewed a video of similar {1} at a recent NCNAAPT mtng, w/ an
unexpected result (for bc i.e. )
{1} the incident “point mass” was a spring loaded rod. The extended
mass was a symmetrical block resting on rails.
