s4w2: special relativity, simultaneity, dilation and contractions

Note from the author:

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.

What is the primary purpose of Lorentz transformations in special relativity?

According to Einstein's special relativity, what is true about the speed of light in a vacuum?

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

Match the term with its definition:

Draggable item		Corresponding Item
a non-accelerating coordinate system used by an observer to measure the position, motion, and physical properties of objects relative to their viewpoint		Spacetime
Four-dimensional continuum of space and time		Time dilation
a unique path that an object traces through 4-dimensional spacetime, representing its complete history of spatial positions over time		Length contraction
Change in time due to relative speed		Worldline
Change in measured length due to motion		inertial frame of reference

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?

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

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

Required

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

Required

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?

Required

The farther apart two simultaneous events (from one stationary frame of reference) are in space

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?

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.

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
