AP Physics 1: 1.2 Waves

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
