Subject: Do blackholes slow down gradually?

When the quantum foam generates a particle-antiparticle pair and one of them
falls in the black hole, the momentum of the falling particle is combined with
the momentum of the black hole itself, right? And no particle can move faster
than light, so on the side of the black hole that is facing the direction it is
moving, it will absorb more particles and antiparticles than on the opposite
side, gradually reducing the momentum of the black hole, no?
