Since force is related to a change in momentum and not necessarily just to a change in velocity, what would be an example where only the mass of a body changes but not its velocity when subjected to a force?

Answer 1

You don’t have the extremes in the real world.

At newtonian speeds, the change in mass will be negligible. As you approach C, the increase of speed will be negligible.
