Answers

1
Inertial frames are non-accelerating while non-inertial frames do accelerate
True
False
2
What is length contraction?
measurement errors carried forward in an experiment
an illusion of velocity and length due to interplanetary breakup
an object's length while in motion is measured to be shorter
a changing length due to elasticity
3
What is time dilation?
time is measured to move more slowly at one reference frame
clocks turn faster due to higher voltage in the system
reference frames are measured to move more slowly at one time
time moves slower due to a velocity equal to the speed of light
4
What does Einstein's Theory of Relativity state?
distance, time and mass are relative
that e = mc²
all the laws of physics are the same in an inertial frame
the speed of light in a vacuum is equal to π x the radius of pluto
5
E=mc² is:
equal to electricity = mass x speed of a car on the M2 squared
useless
a lie and invented to increase the lore in christopher nolans "oppenheimer"
irrelevant
6
Is the speed of light in a vacuum - ‘c’ - absolute?
False
True
