physics and history Okay Alright Have appalling innit Whose block
in a ball All right Ah block is inside of
all is shown about if a student pushes the ball
to make it roll which of the following convey classified
as a system Select two of the following answers and
here blocked bowels involved Okay let's address the question in
hand which focuses on systems Remember a system is a
collection of objects whose properties influence the motion of things
inside the system A system has an internal structure that's
made up of objects as well as the forces and
fields that those objects create Let's Think about what's happening
with this question Students pushing the ball so that's a
system right the students exerting force on the ball making
it move And in this system the student and the
ball are objects So we know that one of the
correct answers has to be ceased but the ball has
its own internal structure that affects its movement to that's
because as the ball rolls the block will tumble around
inside of it and that can change the balls momentum
in direction so because the ball has its own structure
that influences its movement the ball is its own system
so option b is the other correct answer The block
in this question isn't a system because it doesn't have
an internal structure That's influencing it block for lack of
a better term is just a block so option a
is incorrect The student definitely has an internal structure After
all people are full of gloopy gross things that are
moving around all the time but in this question the
students internal structure really doesn't matter The actions of her
component parts aren't exerting their own influence so we can
rule out option d and remember if you need a
break from all this physics just find a ball jama
block into it and play like the minds did Cool 00:02:05.68 --> [endTime] bouncy
