HSV B.6 - double hit detection and avoidance

[GetMeThere1]

I had actually never thought of these issues until looking at your "referee test" videos. As a physicist then, can you state categorically that the CB CANNOT move forward past the point of OB contact (barring jumping CBs or CBs with topspin that takes hold)? Is this the same principle as the "steel-ball-pendulum" toy, where the number of balls that hit the pack always equals the number that leave? If the CB were heavier than the OB, could you then get forward movement?

If the CB is the same weight, the same size, and level with the OB (i.e., not airborne), then the CB won't move forward immediately after contact. Now, with a slow follow shot, it won't delay very much before moving forward.

The momentum transfer is the same effect as with Newton's Cradle, the toy you mentioned.

Thanks for watching and commenting on so many of my videos. Please help spread the word about my stuff.

@DrDaveBilliards : ...and by definition, when the CB is frozen, or very close to the OB, there's no such thing as "slow rolling" the shot.

Agreed.
