Hidden momentum

Short description: Physics concept

In special relativity, hidden momentum or hidden mechanical momentum is the mechanical momentum (mass times velocity) that is unaccounted for by Newtonian mechanics. The concept of "hidden momentum" has been used in answering "paradoxes" in electromagnetism and other problems, including the Shockley–James paradox,[1] the Mansuripur paradox,[2] and the Aharonov–Casher effect.[3]
