ActivPhysics: 17.1 and 17.2



Q1:  The distance of the moving light clock is longer. If we assume the angle is 45­­0­­ then
distance is 1.414 times longer
Q2:  The time of the stationary light clock is 6.67s and the moving lock is 9.40s
Q3:  No, in your frame of reference the light clock does not travel a longer distance when
moving
Q4:  When velocity of the light clock decreases the time difference decreases.
Q5:  8.004s
Q6: Lorenz Factor = 1.1169~1.12

Relativity of Length
Q1:  The time measurement of the round trip does not matter.
Q2:  If measure form earth, it will be longer.
Q3:  As time decreases, the length needs to be smaller.
Q4:  L = 769.12
