Special Relativity - Physics 12What are "thought experiments" useful for? - answer Imagining topics of special
relativity
What is a postulate? - answer A proposed assumption or a set of rules used in an
assumption
What is the first postulate of special relativity? - answer If two frames of reference move
with constant velocity relative to each other then the laws of physics are the same in
both frames of reference
What about special relativity and acceleration? - answer There is none!
Is light constant? What speed can it go? - answer Yes and it can only go the speed of
light
What is the second postulate? - answer The speed of light is the same in all frames of
reference. Essentially, the speed of light is one number no matter what
Is there a prefered speed frame of reference? - answer No
Explain the double slit experiment: - answerIf light were just made of particles it would
create two light slights and if they were waves they could interact. They all kind of mush
together in rings... a photon has a statisitcal probability of where it is going to be
What does Einstein's general theory of relativity suggest? - answerThat the sun's gravity
bends the path of light
What is time dialation? - answer(Time widening) The idea that a clock that is moving will
run slowly. It also lets us know that time is relative and everything has their own clock
What is the time dialation reason why you can't go the speed of light? - answerBecause
the equation for calculation would become undefined
What is the equation for time dialation and what does it do? - answerT= T1^2/
sr(1-v2/c2) It compares the two different times from different angles in the dialation
triangle
What happens in terms of time dialation when you go faster? - answerYou dialate more
