AP Physics 1: 1.5 Properties of Objects and Systems

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
