Teachers & SchoolsAP Physics 1: 1.2 Waves. Which of the following correctly rewrites the statement?
AP Physics 1 | Waves |
Language | English Language |
And here the potential answers All right Mechanical waves or
disturbances in matter That matter khun b air like when
our mom yells at us for leaving the drawers open
it will matter can be water like when we cannonball
into a pool It can even be a solid like
that around in an earthquake but in all of these
cases the matter isn't transported It just goes up and
down it doesn't move forward It stays there like us
after eating too much spaghetti dinner the wave causes motion
but when the wave has passed the matter is still
in its original position Here's another way to think of
it if we take a jump rope and move it
up and down will create a wave but the jump
rope won't actually go anywhere The wave is energy moving
through the rope but it's not transporting it so the
correct answer here is be matter is disturbed but not
transported Answer is incorrect because waves don't constantly accelerate or
decelerate waves can maintain a velocity or the velocity can
change and answer c is wrong because waves don't transfer
physical or non physical quantities Energy move through a medium
is part of a wave but no quantities or transferred
and we've already discussed why the original statements wrong so
the that's out too well since waves don't transport any
matter this is another reason why spring zahra Good analogy
for the actions of a wave A spring moves back
and forth or up and down without changing its location
We know a lot more about waves now which is
great We're going to go ahead and wrap this up
now so we'll say goodbye That feels a little incomplete
though if only there was some kind of gesture is
something we could do with our hand to add to
the whole goodbye process Huh Huh No no we're stumped
