Resource type: Video/animation
Description: Part of a series of videos showing the glass transition in polymers, and the resulting change in energy dissipation on impact: Close up video at one tenth actual speed of ball bouncing well below Tg (i.e. when glassy). The conformation is frozen, so it is only the interatomic bonds that are strained. The macroscopic deformation is much less and is not observable in the video.
