In free fall, there is no air resistance, so the only force acting upon the object of free fall would only be its weight.
Now the question is, if an object keeps accelerating due to free fall, wouldn't it eventually reach the speed of light? For example, Earth's g=9.81 m/s^2, so over a course...
I know that anything with mass has a conserved energy within it. In that sense, wouldn't it be logical to say that even a paperclip could destroy a city in America (since c is such a huge number.) So in that case, how do you release the energy?
*note: I'm not trying to destroy the world, I...
If gravity is a force, then the moment the object producing gravity is taken away, it should result in gravity taken away instantaneously.
However, why does Einstein say that Newton's classical mechanics are incorrect and that in fact he decided to propose spacetime and not follow what Newton...
if what i stated is not true, then please tell me what "T" stands for and what "T_0" stands for
but then aren't black holes created when a star's mass becomes infinitely big so that it collapses on itself and creates a rip in spacetime? Anyways, if the mass of a black hole is NOT infinity...
First of all, (following Einstein's theory of Gravitational Time Dilation (I'll just call it GTD,)) objects (such as us) age slower near strong gravitational fields than in empty space. The higher the local distortion of spacetime due to gravity, the more slowly time passes. So according to GTD...
