Question

As if the force is constantly increase there is increase in acceleration therefore increase in kinetic energy making velocity increase to infinity but it cannot go beyond velocity of light therefore mass increases to compensate the velocity but then how can blackhole form if any object cannot go beyond the speed of light?

Answer 1

Any object cannot go beyon speed of light and the formation of blackholes is nowhere related.
Stellar black holes form when the center of a very massive star collapses in upon itself.
the escape velocity of blackholes is greater than the speed of light so the light itself cannot escape from a blackhole and hence it appear black and called a blackhole
