1 Special Relativity By Jackson Andrews

2 Introduction Special relativity is the theory of the relationship between space and time. It was originally proposed in 1905 by Albert Einstein. It is centered around two main postulates: The Principal of Relativity The Principal of Invariant Light Speed

4 principal of relativity
All the laws of nature are the same in all uniformly moving frames of reference. Moving at a constant velocity has the same effect as being completely still.

5 The Principal of Invariant light speed
In a vacuum, light will always travels at the same velocity.

6 Relativity of simultaneity
Two events, simultaneous for one observer, may not be simultaneous for another observer if the observers are in relative motion.

7 Time dilation Moving clocks are measured to tick more slowly than an observer's "stationary" clock.

8 Maximum speed is finite
No physical object, message or field line can travel faster than the speed of light in a vacuum.

9 Mass–energy equivalence
E = mc2, energy and mass are equivalent and transmutable. The mass of an object or system is a measure of its energy content.

10 Length contraction Objects are measured to be shortened in the direction that they are moving with respect to the observer.
