Items or partners contacted and set in motion during the act of volleying can potentially lead to NVZ faults. It's essential to determine when momentum ends, so players can know the point in time after which they, and any contacted item or partner, may make contact with the NVZ without causing a fault. This expanded definition, along with revised 9.B.1., will clarify when momentum ends for contacted items or partners.

Any scenario where a paddle, hat, partner, or anything contacted during a player's act of volleying, continues independently in motion as to potentially cause a NVZ fault.
