1
The alien ship flies horizontally at 0.5c. From Tina's perspective, the aliens onboard...
have the same time as him
move in fast motion
move in slow motion
2
How fast must a spaceship travel if it is to become 30% as long as its rest length?
0.30c
0.91c
0.95c
0.84c
3
Satellites travel at a very high speed, so we (on Earth) measure satellite clocks to run:
backwards
normal... (by now you know it's not this one)
slow
fast
4
The speed of light...
is slowest through the vacuum of space
will be slower with respect to fast moving objects
is the same for all observers, regardless of their motion
depends on how fast the observer is moving
5
Which of the following would be considered a non-inertial reference frame?
A volleyball that is in freefall toward Earth
An airplane banking, following a curved path
A cat running down the stairs at constant speed
A man standing on a chair
6
The alien ship flies past at 0.5c. From Tina's perspective, the alien ship is:
inferior to him in every way
less length (nose to tail)
less width (side to side)
less width and less height
7
Which of the following is true of proper time?
it is measured for an object at rest
it is always larger than dilated time
it's measured by an observer at rest w/respect to 2 events
it's measured by an observer moving w/respect to 2 events
8
An alien ship flies over a stadium at 0.5c. How long do they measure the 100 m long field as?
50 m
100 m
86.6 m
115.5 m
9
From the perspective of the aliens, how will they see Tina?
as a hero
moving in slow motion
moving in fast motion
moving at a normal rate
10
Which of the following is FALSE?
In a vacuum, c varies slightly based on light frequency
The laws of physics are the same in all reference frames
every inertial reference frame is equally valid
The speed of light is the same for all observers
