There is only about 16 minutes of video in this flipped classroom. But its hard stuff. find other sources to try to work through it until you feel like you aren't entirely lost.

Question 5
5.

Time dilation describes the concept that the passage of time is not the same universally, the faster you are moving, the slower time is moving for you compared to something else. Where else do you see this?

Question 6
6.

Just watch the first two explainers (college and above goes into weird places)
do you have any questions on the light clock idea?

Question 7
7.

Now watch the video on Simultaneity Do you have any questions.

Question 8
8.

If any of you said no to the last question - I don't believe you. Try again.

Question 9
9.

Is this sort of like thunder and lightning? they happen at the same time, but you see one before you hear the other one? Why or why not?

Question 10
10.

Question 11
11.

We watched part of this in class, I didn't realize it wasn't included in the FC. I have added it.
watch the whole thing this time, do you have any questions?

Question 12
12.

Part of the problem with understanding simultaneity, understanding time is important. it explains some of the same concepts, but links to the g
arage paradox.

Question 13
13.
What is the primary purpose of Lorentz transformations in special relativity?
To convert between different inertial reference frames
To calculate the speed of light in a vacuum
To determine the mass of subatomic particles
) To measure the curvature of spacetime
According to Einstein's special relativity, what is true about the speed of light in a vacuum?
It varies depending on the observer's motion
It is constant in all inertial reference frames
It can be exceeded by certain particles
It changes with the strength of gravity
What happens to time for an object moving at high speeds relative to an observer? a) Time passes more quickly for the moving object b) Time passes more slowly for the moving object c) Time passes at the same rate for both the object and observer d) Time stops completely for the moving object
Time passes more quickly for the moving object
Time passes more slowly for the moving object
Time passes at the same rate for both the object and observer
Time stops completely for the moving object
Match the term with its definition:
Change in measured length due to motion
Spacetime
a non-accelerating coordinate system used by an observer to measure the position, motion, and physical properties of objects relative to their viewpoint
Time dilation
Change in time due to relative speed
Length contraction
Four-dimensional continuum of space and time
Worldline
a unique path that an object traces through 4-dimensional spacetime, representing its complete history of spatial positions over time
inertial frame of reference
The farther apart two simultaneous events (from one stationary frame of reference) are in space
The smaller the gap in time would be to a fast moving observer
the larger the gap in time would be to a fast moving observer
the gap would be there but it depends on the speed of the observer, not the distance in space
how time dilation works
how length contraction works
why two events may not be considered simultaneous to a one abserver but not to another
why non-simultaneity is not like the thunder/lightening comparison
time is wacky and way less normal that everyone thinks.
I've got this
I'm fuzzy
so confused
