Thank you We sneak and here's your shmoop du jour

00:05

Brought to you by blocking ball a fun game that

00:08

was invented by the ancient mayan and became popular in

00:12

america in the late eighteen hundreds Actually we should probably

00:15

mention that we made all that up Look this is

00:17

physics and history Okay Alright Have appalling innit Whose block

00:21

in a ball All right Ah block is inside of

00:23

all is shown about if a student pushes the ball

00:26

to make it roll which of the following convey classified

00:28

as a system Select two of the following answers and

00:32

here blocked bowels involved Okay let's address the question in

00:37

hand which focuses on systems Remember a system is a

00:41

collection of objects whose properties influence the motion of things

00:44

inside the system A system has an internal structure that's

00:48

made up of objects as well as the forces and

00:50

fields that those objects create Let's Think about what's happening

00:54

with this question Students pushing the ball so that's a

00:57

system right the students exerting force on the ball making

01:01

it move And in this system the student and the

01:04

ball are objects So we know that one of the

01:07

correct answers has to be ceased but the ball has

01:11

its own internal structure that affects its movement to that's

01:15

because as the ball rolls the block will tumble around

01:19

inside of it and that can change the balls momentum

01:22

in direction so because the ball has its own structure

01:25

that influences its movement the ball is its own system

01:29

so option b is the other correct answer The block

01:32

in this question isn't a system because it doesn't have

01:34

an internal structure That's influencing it block for lack of

01:38

a better term is just a block so option a

01:40

is incorrect The student definitely has an internal structure After

01:44

all people are full of gloopy gross things that are

01:47

moving around all the time but in this question the

01:50

students internal structure really doesn't matter The actions of her

01:53

component parts aren't exerting their own influence so we can

01:56

rule out option d and remember if you need a

01:58

break from all this physics just find a ball jama

02:01

block into it and play like the minds did Cool 00:02:05.68 --> [endTime] bouncy
