Sample Questions Ch. 35 - Special
Theory of Relativity
The place form which motion is observed and measured is called - Answer- a frame
of reference
The speed of light is - Answer- constant for all observers
What is special about the ratio distance traveled per unit of time? - Answer- it is
constant for light
According to the special theory of relativity, all laws of nature are the same - Answer-
in all uniformly moving reference frames
How fast would a light beam appear to Einstein is her were traveling in the same
direction at 90% of the speed of light? - Answer- c
A postulate of special relativity is that the speed of light - Answer- for all observers is
a constant
Two lightning bolts are seen to strike two distant locations at the same time. Seen
from a different location, the two lightning bolts - Answer- may or may not be seen at
the same time
When you run along the hall form one classroom to another you're moving through -
Answer- time and space
All events and all things exist in "the spacetime continuum" with coordinates -
Answer- of distances in three dimensions, and of time

and down between parallel mirrors in 1 nanosecond. An observer at rest outside the
spaceship sees the same up-and-down flash in - Answer- more than 1 nanosecond
The stretching out of time due to motion is called time - Answer- dilation
Compared to clocks in a stationary reference frame, clocks in a moving reference
frame run - Answer- slower
