What does theory of relativity means?
a theory, formulated essentially by Albert Einstein, that all motion must be defined relative to a frame of reference and that space and time are relative rather than absolute concepts: it consists of two principal parts.
What does relativity mean in simple words?
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.
What is special theory of relativity in simple words?
Special relativity is an explanation of how speed affects mass, time and space. As an object approaches the speed of light, the object’s mass becomes infinite and so does the energy required to move it. That means it is impossible for any matter to go faster than light travels.
What happens when you approach the speed of light?
Speed of Light FAQ As an object approaches the speed of light, its mass rises steeply – so much so that the object’s mass becomes infinite and so does the energy required to make it move. Since such a case remains impossible, no known object can travel as fast or faster than the speed of light.
What did Einstein mean by time is relative?
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.
What is theory of relativity in simple words?
Theory of relativity. The theory of relativity, or simply relativity, generally encompasses two theories by Albert Einstein: special relativity and general relativity. Concepts introduced by the theories of relativity include: ⁕Measurements of various quantities are relative to the velocities of observers. In particular, space and time can dilate.
What is relative theory in physics?
(physics) the theory that space and time are relative concepts rather than absolute concepts
How does the theory of relativity affect our perception of time?
The theory of relativity lets us see how gravity interacts with what we perceive to be the physical world. When there are changes to gravity, the structure of time can be altered. This effect has been studied in astronauts as they age slower.
What is Einstein’s theory of relativity?
Einstein’s theory of relativity incorporates two components: special relativity and general relativity. Special relativity involves how the basic particles of the universe interact with one another. It describes what happens in the physical world, with the exception of gravity. That’s where general relativity comes to help.
