General Theory of RelativityGeneral Theory of Relativity - answera more general theory of relativity that takes into
account accelerating (non-inertial) reference frames (and the effects of gravity)
Gravitational Mass - answerthe property of an object that determines how much
gravitational force it feels when near another object (NOTE: Different gravitational
masses have different forces acting between them)
Inertial Mass - answerthe property of an object that determines how much it accelerates
when a given force is applied to it (OR: the ratio of relsultant force to acceleration of an
object) (NOTE: Different inertial masses have different acceleration s when a force acts
on them)
Principle of Equivalence - answera postualte that states there is no difference between
an accelerating frame of reference and a gravitational field
Einstein's closed elevator "thought experiment" - answeran object dropped inside a
closed elevator will accelerate toward the floor - could be explained in one of two ways:
either the elevator is far from any planet but accelerating upward or the elevator is at
rest on the surface of a planet
Spacetime - answerfour dimensional coordinates used to describe any event (three
spatial dimensions and time) (NOTE: Moving objects follow the shortest path between
two points in spacetime) (NOTE: gravitational attraction can be explained by the
warping of spacetime)
Black Holes - answera region of spacetime with extreme curvature due to the presence
of a mass
Center of a black hole (singularity) - answerthe single point to which all mass would
collapse
Surface of a Black Hole (event horizon) - answerwhere the escape speed is equal to
speed of light and within this surface, mass has 'disappeared' from the universe
Schwarzschild Radius (Rs) - answera particular distance from the center of black hole
where escape velocity is equal to the speed of light (nothing within the event horizon
can be communicated to the outside)
