If a star has a mass greater than the Chandrasekhar limit, will it definitely become a black hole in the future or does it need to satisfy additional conditions? Let me explain. Suppose the collapse of a star happens via the formation of the intermediate neutron star stage. Is it possible that t...
Today in my physics class, my teacher said that if one would point a laser into a falling elevator (acceleration because of a gravitational field), an observer inside the elevator would see the light form like a parabola, like i have tried to illustrate here:
He told us this is because the eleva...
I am wondering why a car can accelerate forward even if no forward net force acting on it. See the following diagram.
I don't draw the internal forces due to engine because they don't contribute to the external net force. What am I missing here?
