Why is special relativity called special?
The theory Einstein described is now known as the “special theory of relativity.” It is a “theory of relativity” because it is based on the relativity of inertial motion. The theory of 1905 came to be called the “special” theory to distinguish it from the later extension, “the general theory of relativity.”
What are the postulates of general relativity?
The first postulate is the relativity principle: local physics is governed by the theory of special relativity. The second postulate is the equivalence principle: there is no way for an observer to distinguish locally between gravity and acceleration.
What is the definition of relativity?
1a : the quality or state of being relative. b : something that is relative. 2 : the state of being dependent for existence on or determined in nature, value, or quality by relation to something else.
Who is the father of relativity?
Albert Einstein
What is the opposite of relativity?
Antonyms & Near Antonyms for relativity. autonomy, self-determination, sovereignty.
How is relativity applied?
The theory explains the behavior of objects in space and time, and it can be used to predict everything from the existence of black holes, to light bending due to gravity, to the behavior of the planet Mercury in its orbit.
What is time according to relativity?
In the Special Theory of Relativity, Einstein determined that time is relative–in other words, the rate at which time passes depends on your frame of reference. The faster a clock moves, the slower time passes according to someone in a different frame of reference.
How do you explain time?
In math, time can be defined as the ongoing and continuous sequence of events that occur in succession, from the past through the present to the future. Time is a used to quantify, measure or compare the duration of events or the intervals between them, and even, sequence events.
What is the best definition of time?
1a : the measured or measurable period during which an action, process, or condition exists or continues : duration. b : a nonspatial continuum that is measured in terms of events which succeed one another from past through present to future.
