1
Q
Speed of light
A
c = 3 * 10^8 m/s
2
Q
First Postulate of Relativity
A
for all frames of reference, speed of light is the same
3
Q
Second Postulate of Relativity
A
light emitted from moving source, still goes at speed of light
4
Q
Time dilation equation
A
t = t0 / (sqrt( 1 - (v^2 / c^2) ))
t0: time on clock of stationary observer
t: time on clock of moving object
5
Q
Length Contraction
A
L = L0 * sqrt( 1 - (v^2 - c^2) )
L0: normal length
L: length perceived by stationary observer
6
Q
Mass Effects
A
m = m0 / (sqrt( 1 - (v^2 / c^2) ))
m: new mass of object
m0: original mass of object
