I was mistaken. See my response to @PAllen in post #25.

1. The mass will be concentrated at the singularity. 2. Simple Newtonian mechanics apply. If the mass of the black hole is a million times the mass of the star, the black hole will hardly move at all. If it's three times the mass of the star it will move substantially.KurtLudwig said:What happens to the inertia of a mass falling into a black hole? I am not even sure if I frame the questions correctly. Will this mass reach the center or is mass distributed within the black hole? Is the singularity the whole volume of the black hole or is it a point in the center? If a large star falls into a medium-sized black hole, will the black hole move towards the star, due to gravitational attraction, or will the impact move the black hole away, due to the inertia of the star?
Inertia is the tendency of an object to resist changes in its state of motion. It is a property of matter and is directly related to an object's mass.
As the mass falls into the black hole, its inertia remains the same. However, the effects of gravity become stronger as it gets closer to the black hole, causing the object to accelerate and gain more momentum.
No, the inertia remains the same even as the mass crosses the event horizon. However, the gravitational pull becomes infinitely strong at the event horizon, causing the object to accelerate towards the singularity at the center of the black hole.
No, the effects of gravity become so strong near the black hole that it is impossible to observe the inertia of the falling mass. The black hole's strong gravitational pull also distorts light, making it difficult to see the object.
The concept of inertia still applies inside a black hole, but the extreme gravitational forces make it difficult to measure or observe. Additionally, the laws of physics, including inertia, break down at the singularity at the center of the black hole.
