The wikipedia article on collisions says "collisions between hard spheres may be nearly elastic". It doesn't elaborate nor give a source on the statement. I was wondering about those two conditions. Hardness I understand, but is the spherical shape necessary? Is it about there being a single point of contact? In which case, what if they were non-spherical bodies, but with spherical points of collision, like in the pic?
