General-Relativity
Principle of Relativity
The Principle of Relativity states that: The laws of physics take the same form in every intertial frame. No exception has been found to this principle, and it …

I In an intertial frame of reference (i.e. a frame of reference undergoing zero acceleration), an object at rest stays at rest (or, similarly, keeps its initial …

Newtonian Spacetime differs from Relativistic spacetime in that time is considered an absolute (i.e. ). Transformations between reference …

Above are two frames in Cartesian coordinates, and . We have coordinates , which define our dimensions. Inertial Frame An …

In Newton’s formulation of spacetime, time is an absolute; meaning that every observer experiences the same flow of time. Assuming an inertial frame with …
