Friction force.
Reason: momentum of a closed (isolated) system is conserved; dissipative external forces like friction (air resistance, pivot friction) exert net external impulses that remove momentum (and convert mechanical energy to heat). Magnetic/electrostatic forces are conservative/internal unless an external field is applied, and the strong force is irrelevant at this scale.
