Two lines of balls - one set larger than the other - shown colliding into one another and rebounding into opposite directions.

Label Text:
In Collision of Two Balls, Berenice Abbott uses a stroboscopic camera to capture the momentum of two balls before and after they collide. Abbott ensured that each ball moved with a constant velocity, signified by the even spacing between shots. At the collision, the transfer of energy and momentum changes each ball's path forever. After the collision, the balls go their separate ways, but in what directions? Interestingly, we cannot know this, as the movie of this collision played in reverse would create the same stroboscopic image.
